Semiclassical Approaches to IR Issues in Quasi de Sitter Universes

Who: Martin S. Sloth (CERN)
When: Monday, December 13, 2010 at 14:15
Where: The CP³ meeting room

Abstract:
Using simple semiclassical relations it is possible to show that the conventional cosmological correlation functions are affected by significant IR corrections in quasi de Sitter space-times when averaged over very large volumes (in the “large box”). The IR effects apparently imply a breakdown of perturbation theory in the large box on sufficiently long time scales, for example the time between self-reproduction and reheating in chaotic inflation. An interpretation of the apparent breakdown of the perturbative expansion of gravity will also be discussed.

Cloudy with certainty of rain: Effects of QCD Radiation on global inclusive variables

Who: Andreas Papaefstathiou (University of Cambridge)
When: Friday, December 10, 2010 at 11:00
Where: The CP³ meeting room

Abstract:
Amongst the many observables that could be of use in the search for New Physics at hadron colliders, those that do not depend on detailed hypotheses about the structure of the final state may be the most suitable for an initial general survey of the high-energy frontier. Quantities of this type have been named global inclusive observables and may present a useful way of determining the scale of the New Physics without detailed reconstruction of the events.
I will be presenting work towards understanding the QCD effects on these variables, through all-order resummation, as well as the effects of any invisible particles originating from decays in the hard process. Moreover I will describe a model-based phenomenological method of determining the effects of the so-called`underlying event’ on global inclusive variables. This talk is based on work which appeared in arXiv:0903.2013 and arXiv:1004.4762.

Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) for direct analysis and imaging og biological samples

Wednesday December 8th at 15:15

Venue: BMB Seminar Room
Coffee and tea at 15:00

Abstract:
Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) is a relatively new technique for direct analysis of surfaces with mass spectrometry under ambient conditions. In DESI-MS an electrospray is directed towards a surface positioned in the proximity of the atmospheric interface of a mass spectrometer. The electrospray ionizes compounds present on the surface which are subsequently analyzed by the mass spectrometer, thereby providing a rapid and highly specific analysis of the contents of the surface. By scanning the sample systematically below the electrospray while recording mass spectra, chemical images can be generated, showing the distribution of compounds on the surface, similarly to TOF-SIMS imaging, but under ambient conditions and with a preference for relatively polar molecules.

The talk will show the construction of various DESI ion sources, including a recently constructed source for DESI imaging, and present examples of applications for imaging of lipids in animal tissue sections and imaging of secondary metabolites in plant material. Furthermore, the construction and application of a recently invented Low Temperature Plasma ion source will be discussed.

D-branes in String Theory

Who: Rodolfo Russo (Queen Mary, U. of London)
When: Friday, November 26, 2010 at 11:30
Where: The CP³ meeting room

Abstract:
The aim of these lectures is to provide an introduction to D-branes in type II string theories. I will start from the basic definition of D-branes as the objects supporting the fundamental string endpoints, then I will describe them from the closed string point of view and I will discuss their “gravitational” backreaction. I will conclude by giving a brief overview on how D-brane bound states have been used to model black holes in string theory.

Graphene – how to control its electronic properties by chemical functionalization.

Associate Professor Liv Hornekær,
Department of Physics & Astronomy, Aarhus University

Wednesday November 24th at 15:15 in the BMB Seminar room.
Coffee and tee at 15:00

Abstract:
Graphene, a single layer of graphite, has unique physical properties which make it interesting both as a playground for studying new fundamental physics and as a possible future material for electronic circuit fabrication. Most notably the charge carriers in graphene have very high mobility, exhibit ballistic transport properties and behave like mass-less relativistic Dirac fermions. These characteristics potentially make graphene an ideal material for electronic device fabrication. However, graphene lacks a bandgap around the Fermi level, which is the defining concept for semiconductor materials and essential for controlling the conductivity by electronic means. Several approaches to engineer a bandgap opening in graphene have been suggested, but until recently experimental realizations have been limited to gap openings too small for room temperature operation. By chemically functionalizing graphene on an Ir(111) substrate we have demonstrated the opening of a bandgap of ~1.0 eV, sufficiently large for real applications. An introduction to graphene research will be given and the potentials and limitations of chemical functionalization of graphene will be discussed.

Seeing Signals of Dark Matter in Cosmic Rays?

Who: Marco Cirelli (CERN)
When: Monday, November 15, 2010 at 14:15
Where: The CP³ meeting room

Abstract:
Dark Matter constitutes more that 80% of the total amount of matter in the Universe, yet almost nothing is known about its nature. A powerful investigation technique is that of searching for the products of annihilations of Dark Matter particles in the galactic halo, on top of the ordinary cosmic rays. Recent data from the PAMELA and FERMI satellites and a number of balloon experiments have reported unexpected excesses in the measured fluxes of cosmic rays. Are these the first direct evidences for Dark Matter? If yes, which DM models and candidates can explain these anomalies and what do they imply for future searches? What are the constraints from other gamma rays measurements and cosmology?

CP³ Lecture v. Marcello Messina (Bern University)

Towards the Detection of Cosmological Relic Neutrinos with Neutrino Capture on Beta Decaying Nuclei

Who: Marcello Messina (Bern University)
When: Friday, November 12, 2010 at 12:30
Where: The CP³ meeting room

Abstract:
The topic of the seminar will be on a novel idea for the detection Cosmological Relic Neutrinos (CRN) and more in general, for the detection of neutrinos of vanishing energy. This idea is described in detail in the paper [1]. The method is based on the fact that neutrino interactions on beta-instable nuclei have the key feature of requiring no energy threshold for the neutrino interaction. Furthermore, in reference [1] a very interesting feature of v is shown for neutrino interacting with beta-instable nuclei: even if the kinetic neutrino energy vanishes v keeps a constant value depending only on the considered target nucleus. This allows, in principle, the detection of neutrinos of vanishing energy. In order to achieve high detection sensitivity one needs for CRNs discovery new developments are necessary in the field of detectors technology. In the seminar I will describe several detection technologies and eventually I illustrate a possible experimental approach for the discovery of the Cosmological Relic Neutrinos.

‘t Hooft Nobel Lecture: Black Holes in Elementary Physics

Who: Gerard ‘t Hooft (Universiteit Utrecht)
When: Tuesday, November 2, 2010 at 16:00-17:00
Where: O100

Abstract:
In Physics, black holes are known as extremely dense forms of matter, of which, from the outside, only the gravitational force can be
detected. Astronomers observe such object ate various spots in the Universe.
When in laboratories on earth elementary particles are made to collide with the strongest possible force, these collisions are by far not energetic enough to produce black holes. However, we can try to imagine collisions that are so energetic that black holes do form, and then ask ourselves what exactly might happen then. The question is important because it turns out that our theoretical understanding falls short at this point. The gravitational force is so special that all beautiful theories we have today about the particles and the forces between them cannot describe it. Do black holes obey the laws of quantum mechanics? Are black holes also subatomic particles and vice versa? If so, our theories must be revised. This can lead to fundamental new insights about very basic features in physics, and give us new tools to describe space, time, and matter.

Particle therapy – how advanced ion accelerators are used to fight cancer

Wednesday September 22 2010 at 15:15 in the BMB Seminar Room

Coffee/tea at 15:00
The talk will be given in English.

Abstract:
Despite the success of radiotherapy with X-rays or electrons, this form of therapy has very limited applicability in those cases where tumors are close to tissue or organs with high radio-sensitivity. Among those are tumors in head & neck, pelvis (prostate, bladder, rectum), the gynaecological system, lung, CNS, paraspinal/para-ortic, limbs, etc. In those cases it is advantageous to apply energetic light ions. Due to the strong increase of the ionization density at low ion velocities, the largest fraction of the biologically effective dose is concentrated at the end of the ion trajectory. Very confined dose distributions are achieved by placing multiple “Bragg peaks” from ions of different energies into the tumor region.

In order to deposit ions into the deepest lying regions of the human body, energies of up to 200 MeV are needed for protons, or 450 MeV/n for carbon ions. Those energetic ion beams are produced by relatively large accelerators which require floor space of several hundred square meters. An overview over existing particle therapy systems will be given, with emphasis on the latest developments on combined proton-carbon systems, as the one recently inaugurated in Heidelberg and one being built in Marburg, Germany. In addition, recent efforts to design more compact particle therapy systems will be presented.

Renormalization Group Approach to QCD with Many Flavors

Who: Jens Braun (Jena University)
When: Monday, September 20, 2010 at 14:15
Where: The CP³ meeting room

Abstract:
Abstract: QCD with many quark flavors has drawn a lot of attention in the past few years. In this talk we discuss the behavior of four-fermion operators in the presence of gauge fields. Based on the renormalization group flow of these operators we then analyze the phase structure of QCD with many flavors in the chiral limit. Moreover, we present universal scaling relations for physical observables such as the critical temperature or the chiral condensate as a function of the flavor number near the conformal window. We argue on general grounds that the associated critical exponents are related to the critical exponent of the running gauge coupling at the Caswell- Banks-Zaks infrared fixed point.

Gas-phase spectroscopy of biomolecular ions: Porphyrins and metalloporphyrins

Wednesday 8th September 2010 at 15:15 in the BMB seminar room

Coffee/tea at 15:00
The talk will be given in English

Abstract:
The electronic structure of a biochromophore (i.e., light absorber) is strongly perturbed by its surrounding environment, e.g., water or amino acid residues within protein pockets or crevices. To reveal the intrinsic electronic properties, it is therefore necessary to study isolated molecules in vacuo. Many biochromophores are ionic in their natural environment, which renders experiments complicated as it is not possible to produce enough absorbing species for traditional light transmission spectroscopy. In Aarhus we have developed state-of-the-art apparatus to record gas-phase absorption spectra of macromolecular ions. The technique is based on the combination of an electrospray ion source, a multipole ion trap for pre-storage, an electrostatic ion storage ring, and pulsed tuneable lasers and relies on measurements of the delayed dissociation of photoexcited ions (action spectroscopy). In this talk I will present some recent results for porphyrin and metalloporphyrin ions. One important target system is heme that is a porphyrin with an iron atom located in the center bound to four ring nitrogens. It colors blood red and is located in hydrophobic pockets of heme proteins with minimal access of water.

STRONGBSM Kickoff Meeting

When: August 16-19, 2010
Where: SDU, Odense, Denmark

The goal of the STRONGBSM network is to boost career perspectives of early-stage researches (ESR) and young experienced researchers (ER) within the extremely competitive and highly demanding field of particle physics now working at the highest energy frontier ever reached by humans. We will prepare a new generation of world leaders for both the academic and the private sectors. The cocktail of strong academic and powerful industrial partners will further make research careers more attractive to young minds. This will be achieved via a trans-national research training throughout Member States and Associated countries as well as our trans-ocean collaborations.

STRONGBSM partners are world leaders in models of dynamical electroweak symmetry breaking and their impact in particle physics and cosmology, in analytic and lattice studies of the phase diagram of strongly coupled theories as function of number of flavours, colours, matter representation, temperature and matter density, and in new approaches on how to simulate supersymmetric theories on supercomputers.

The meeting will start the operations of the consortium with the definition of the work-packages for the project and the planning of future activities.

Celebration for Jack Sabin

Fri, 09 Jul 2010 14:00:00 GMT

July 9 - 11, 2010Jack Sabin, who has for many years been an Adjunct Professor at SDU in addition to his primary position at the University of Florida, has reached his 70th birthday and we are arranging a celebration of this important event. The celebration will take the form of a scientific conference at the Sandbjerg Estate (near Sønderborg), July 9-11, 2010. The organizing committee for the conference consists of myself, Rektor Jens Oddershede, and Professor Nils Yngve Öhrn of the University of Florida.

We would like Jack's colleagues at SDU to be aware of our plans and invite them to take part. It is possible either to be in residence at Sandbjerg for two days (arrive July 9, depart July 11), or to come for the day on Saturday July 10. On July 10 there will be morning and afternoon scientific sessions, and a banquet in the evening. The scientific program features two speakers who are members of the U.S. National Academy of Science (Josef Michl and Mark Ratner) and a number of other prominent scientists, and should be of interest to many at SDU.

Find the circular for the Sabin Fest on the web.

We have to give the Sandbjerg Estate an accurate meal count, and therefore persons wishing to participate will need to register in advance. They can do so in a preliminary way from the web site, and within a few days we will have a site running at SDU that can take payments for the banquet or all-day participation. Anyone who wants to come is welcome, but we need them to sign up no later than June 15.

The Dark Side of the Universe: From Small to Large

Who: Martin Sloth (CERN)
When: Monday, June 28, 2010 at 11:00
Where: The CP³ meeting room

Abstract:
After a brief introduction to cosmology, I will try to shed some light on the dark side of the universe. It has been said that we know a lot about the universe, but understand very little. I will try to explain what we do understand about the primordial phase of inflation that gave birth to our present universe, about dark energy that dominates the energy density of the universe today, and about dark matter that is the dominant form of matter in the universe. Because everything that is large in the universe today origins from something that was once very small, these questions form an intricate link between particle physics and cosmology.

Abstract:
I will give a brief introduction to particle physics and a discussion of some of the outstanding questions which we hope the LHC will provide answers to, e.g. mass generation. I will then move on to discuss some of the challenges to the current theoretical understanding of the Standard Model of particle physics, which will need to be solved in order to maximise the potential of the LHC, and cleanly extract any hints of new physics. In particular, I will discuss how the blessing of the high centre of mass energy provided by the LHC (in terms of a large potential for the discovery of new physics) requires us to solve ever more complicated problems within the Standard Model.

Abstract:
Dark matter can be constrained via particle physics experiments like LHC, direct search experiments like CDMS, astrophysical and cosmological observations. The input and the interplay of all these different sectors are important in order to understand the nature of dark matter. I am going to argue that astrophysical constraints arising from compact stars can potentially impose severe constraints on dark matter candidates.

Abstract:
We describe the general features of hadronic final state at hadron colliders, highlighting the importance of infrared and collinear safety to devise observables that reflect the underlying quark-gluon energy-momentum flow. We then introduce jets and event shapes, the two observables that are mostly used for studies of hadronic final states. We finally discuss the amount of information that can be extracted at the LHC from measurements of event shape distributions.

The Novel World of Quarks and Gluons

Who: Stanley J. Brodsky (CP³-Origins & SLAC, Stanford)
When: Monday, June 7, 2010 at 14:15
Where: The CP³ meeting room

Abstract:
One of the triumphs of theoretical physics of the twentieth century was the development of Quantum Electrodynamics (QED), the fundamental theory of electrons and photons. QED not only describes the physics of the atom with extraordinary precision, but also the basic properties of the electron itself. The corresponding problem in particle and nuclear physics is to accurately describe the structure and interactions of hadrons, such as the proton and neutron, in terms of their fundamental constituents: the quarks and gluons of Quantum Chromodynamics (QCD). In this talk I will discuss a number of novel features of QCD such as “color transparency” and “intrinsic charm”, phenomena which were unexpected from conventional approaches to nuclear and particle physics. There are also important analogs between atomic and hadronic physics. For example, the light-front methods which underlie phenomenology in high energy physics also have remarkable advantages for describing the wavefunctions of atoms in motion. Conversely, the production of relativistic antihydrogen has provided important insight into the conversion of quarks and gluons of QCD into hadrons at the amplitude level. I will also briefly review how mathematical methods based on an extra space dimension brings new insights into fundamental problems in hadron physics.

Low-Energy Baryon Properties

Who: Willi Plessas (University of Graz)
When: Friday, May 21, 2010 at 14:15
Where: The CP³ meeting room

The description and understanding of low-energy baryon properties such as the mass spectra, electroweak form factors, and some selected reaction processes will be addressed. In particular, results calculated in a relativistically invariant framework along constituent quark models will be discussed in view of properties of low-energy quantum chromodynamics and in comparison to experiments as well as lattice calculations. It will be demonstrated that it is most essential to incorporate the symmetries of quantum chromodynamics, remaining after spontaneous breaking of chiral symmetry, and of special relativity.

Interrogating biology with nucleic acid-instructed compounds and assemblies

Guest speaker:
Prof. Dr. Oliver Seitz
Institute of Chemistry,
Humboldt-University Berlin, Germany

Abstract:
A multitude of mutual recognition events orchestrates the complex networks of interactions between biomacromolecules. These recognition events often are mediated by dedicated interaction modules, which govern protein-protein and protein-nucleic acid binding. One of the chief aims of current research in medicinal chemistry, chemical biology and synthetic biology is to deliberately interfere with select recognition events. Small molecule inhibitors of protein-ligand interactions have been used with great success. However, this approach has limitations when protein-protein and protein-nucleic acid interactions are targeted. A different approach is taken up in this presentation. Naturally occuring recognition motifs are considered as role models that are equipped with new functions and fashioned into tools to enable a smart control of biomolecular interactions. It is shown that nucleic acid driven recognition processes allow the control of chemical and biological properties of chimeric molecules. We demonstrate that nucleic acid hybridization can be employed as a means to control the conformational state of a peptide. This approach offers new opportunities to the design of switchable biomolecular recognition. Hybridization processes can be used to trigger chemical reactions which allow amplified DNA/RNA detection or gene encoded formation of drug-like molecules. Furthermore, nucleic acid architectures offer intriguing opportunities for the multivalent presentation of ligands because a) oligonucleotide synthesis provides monodisperse material, b) the valency of the ligand display can readily be controlled by programmed self-assembly based on nucleic acid hybridization and c) the well-known base-pairing rules allow Ångström-scale positioning of functional groups alongthe rigid nucleic acid helix.

The talk will be given in English.

Abstract:
MEMPHYS is an interdisciplinary research center funded by the Danish National Research Foundation for the period 2001-2011. The Center is concerned with parallel experimental and theoretical research within the broad fields of physics and physical chemistry of biological systems. The main focus is on developing molecular descriptions of the physical and physico-chemical properties of membrane systems and investigating how these properties control membrane function. The Center exploits a multitude of theoretical and experimental methods and techniques, including molecular modeling and computer simulation techniques, thermodynamic measurements, monolayer techniques, advanced microscopy and biophotonics, mechanical micro-manipulation, scattering techniques, as well ultra-sensitive surface-probe techniques and single-molecule detection methods.

I will illustrate our mode of working via a number of case studies: new membrane models, lateral domain organization of membranes, the functioning of membrane proteins, ligand-receptor interactions, enzymatic activity at membranes, properties of biological poly-electrolytes, and novel principles for drug delivery.

I will outline the future perspectives for biological physics at SDU in light of the establishment of the new centers for nanomedicine (NanoCAN) and bioimaging (DaMBIC) as well as the relocation of the medical faculty to the main campus. I will also offer some comment on issues related to the establishment and operating of centers of excellence at Danish universities.

Microscopic spectra at finite lattice spacing

Who: Kim Splittorff (NBI)
When: Monday, May 17, 2010 at 14:15
Where: The CP³ meeting room

Chiral Random Matrix Theory and Chiral Perturbation Theory has given us extremely useful tools to extract physical observables from lattice QCD simulations. For example, it is possible to determine the infinite volume value of the chiral condensate from finite volume simulations of Lattice QCD. The tools are based on exact analytic computations of the distributions of the smallest (microscopic) eigenvalues of the Dirac operator in a finite volume. This talk presents the first results for the low lying microscopic spectrum of the QCD Dirac operator at nonzero lattice spacing. The results open a novel analytical approach to lattice gauge theory at finite lattice spacing and are crucial for establishing a stable domain for numerical simulations.

Creating and Analysing Tiny Structures using Ion Beams

Dr. Jens Jensen
Department of Physics, Chemistry and Biology,
Linköping University, Sweden.

Thursday 29^th of April 2010 at 15:15 in BMB Seminar room

Coffee/tea at 15:00

The talk will be given in English.

Abstract:
Material structures with nano-scale dimensions, such as thin layers, wires, pores, composites or an ensemble of tiny precipitates, have many interesting functional properties making them of great interest for a wide range of applications.

Fabrication of well-defined nanostructures is still a major challenge and many diverse approaches and methods are used to create nano-structured materials. Many unique properties are related to nano-structures, and understanding the correlation between the material properties of a system and its nanometre-scale structure is critical for the fabrication of novel functional materials. Characterising and analysing materials on a nano-scale is therefore of fundamental importance for advanced material science.

In this talk I will discuss the possibilities of using ion beams within material science to create and even analyse structures on the nano-scale. I will show examples of nano-structures, having interesting chemical and physical properties, which have been created in a wide variety of materials by different types of ion technologies. Possible applications of the created structured material will be presented. Furthermore, examples of investigating and analysing tiny material features using ion beam analytical instruments will be demonstrated. Advantages and disadvantages, different effects and problems occurring using the presented ion techniques will be discussed.

I will discuss the various mechanisms potentially at work in hadroproduction of heavy quarkonia at RHIC, Tevatron and LHC energies in the light of computations of higher-order QCD corrections both in the colour-singlet (CS) and colour-octet (CO) channels. Besides, I will discuss new observables meant to better discriminate between these different mechanisms, including associated production and correlation measurements. On the other hand, I will show how the kinematics specific to the J/psi production matters for the extraction of Cold Nuclear Matter effects, e.g. the shadowing of the gluon distribution in nuclei.

Cold Electroweak Baryogenesis from Standard Model CP-violation

Who: Anders Tranberg (Helsinki)
When: Thursday, April 15, 2010 at 12:30
Where: The CP³ meeting room

Abstract:
The origin of the observed matter-antimatter asymmetry in the Universe must be sought in high-energy processes within the first second after the Big Bang. Scenarios of this “Baryogenesis” within the Standard Model of particle physics has hit two stumbling blocks: 1) CP-violation is too small at high (electroweak scale) temperatures; and 2) the electroweak phase transition is too weak to provide the necessary departure from thermal equilibrium.
We consider an alternative scenario, Cold Electroweak Baryogenesis, where the electroweak transition at the same time provides post-inflationary reheating. In this case, neither 1) nor 2) apply, and we demonstrate by direct numerical lattice simulations that the observed asymmetry can be reproduced, including only Standard Model CP-violation.

The last couple of years have witnessed many intriguing breakthroughs in the computation and the understanding of the analytic structure of amplitudes in field theories. In this talk we will discuss such new twistor space inspired methods for amplitude computation and see how for example simple results for tree amplitudes can be recycled to give simple results at loop level via unitarity. We will also discuss hidden symmetries in amplitudes in Yang-Mills theory and gravity and discuss how such amplitudes can be related through newly found monodromy and KLT relations.

Seesaw mechanisms of neutrino masses: naturalness, testability and trivialization

Who: Zhi-zhong Xing (IHEP, Chinese Academy of Sciences, Beijing)
When: Monday, March 22, 2010 at 14:15
Where: The CP³ meeting room

After outlining some popular ways to go beyond the standard model so as to generate finite neutrino masses, I focus on several typical seesaw mechanisms and discuss how to get a balance between theoretical naturalness and experimental testability for them. Besides possible collider signatures at the Large Hadron Collider, new and non-unitary CP-violating effects are also expected to show up in neutrino oscillations for most of the TeV-scale seesaw scenarios. Today, however, the seesaw idea is being trivialized by a number of “additive” and “multiple” versions of seesaw mechanisms.

QCD Like Theories at Next-to Next-to Leading Order

Where: The CP³ meeting room

Abstract:
We calculated the vacuum-expectation-value, the meson mass and the meson decay constant to next-to-next-to-leading-order in the chiral expansion for QCD-like theories with general N_F degenerate flavours for the cases with a complex representation, a real and a pseudoreal representation, i.e. with global symmetry and breaking patters SU(N_F)_L*SU(N_F)_R -> SU(N_F)_V, SU(2N_F) -> SO(2N) and SU(2N_F) -> Sp(2N_F). Our results should be useful for lattice calculations for dynamical electroweak symmetry breaking and finite baryon density.

From Random Walks to Dark Matter Haloes

Who: Antonio Riotto (CERN & Padua)
When: Monday, March 15, 2010 at 14:15
Where: The CP³ meeting room

In the current cosmological theory large-scale structures grew via gravitational instability from small-amplitude density fluctuations generated in the very early Universe. Dark matter haloes condense out of these initial fluctuations. This process can be studied by N-body simulations, but it is important to be able to understand the results in simpler terms. We describe a method which is based on the path-integral formulation of field theory to compute the dark matter distribution and is mapped into the so-called first-passage time problem of a random walk in the presence of a barrier.
We show that the resulting halo mass function is in remarkable agreement with the existing simulations, without any ad hoc coefficients.

S(3) Symmetry behind Quark and Lepton Masses and Flavor Mixing

Who: Zhi-zhong Xing (IHEP, Chinese Academy of Sciences, Beijing)
When: Friday, March 12, 2010 at 12:30
Where: The CP³ meeting room

Abstract:
Current experimental data indicate that the spectra of “bright” masses shouldn’t be anarchical. We conjecture that the S(3) flavor permutation symmetry and its breaking might provide a simple way to understand the wide mass gaps between top, bottom, tau and their lighter counterparts, the narrow gaps of three neutrino masses, the smallness of three quark mixing angles, and the largeness of two lepton mixing angles. Could one stone really kill four birds?

Abstract:
G protein-coupled receptors are cell membrane proteins which are activated by a broad range of compounds ranging from light to large proteins. They control many physiological functions and not surprisingly they are target for ~40 % of current marketed drugs. In 2004 we reported the cloning and tissue expression of a novel human family C G-protein coupled receptor, termed GPRC6A. Using molecular modeling of the agonist binding site we predited L-alpha-amino acids as being the endogenous agonist which was subsequently confirmed in pharmacological experiments in Xenopus laevis oocytes and mammalian cells. The most active agonists were basic L-alpha-amino acids, L-arginine, L-lysine and L-ornithine. We have developed efficient pharmacological assays based on measurement of intracellular calcium and inositol phosphate levels in mammalian cells, which have been used to characterize a range of commercially available L-arginine and L-lysine analogs and allosteric modulation by calcium and magnesium ions. In order to study the physiological function of the receptor we have developed a GPRC6A knock-out mouse, which has so far been used to show that the GPRC6A receptor does not have a function in bone under normal physiological conditions. Most recently, we have also developed a GPRC6A specific antagonist using a chemogenomic approach, which will likewise be used to elucidate the function of the receptor.

In some classes of WIMP models, the Higgs boson could be copiously produced in association with a photon from dark matter annihilations in the center of our galaxy. The resulting photon spectrum possesses a line whose energy reflects the mass of the Higgs and of the WIMP and whose intensity depends on the WIMP spin and statistics. I will discuss how gamma-ray telescopes such as Fermi could provide information on the Higgs and dark matter complementary to that obtained at the LHC.

Friday, February 12, at 12:30pm in the CP3 meeting room,

Stefano Di Chiara (CP3-Origins) will give a talk with the title "Minimal Super Technicolor".
Everybody is welcome to participate.

Abstract:
“We introduce novel extensions of the Standard Model featuring a supersymmetric technicolor sector (supertechnicolor). As the first minimal conformal supertechnicolor model we consider N = 4 Super Yang-Mills which breaks to N = 1 via the electroweak interactions. This is a well defined, economical and calculable extension of the SM involving the smallest number of fields. It constitutes an explicit example of a natural superconformal extension of the Standard Model featuring a well defined connection to string theory. It allows to interpolate, depending on how we break the underlying supersymmetry, between unparticle physics and Minimal Walking Technicolor. We consider also other N = 1 extensions of the Minimal Walking Technicolor model. The new models allow all the standard model matter fields to acquire a mass.”

Where: The CP³ meeting room

Hadrons are bound states of quarks and gluons that can be classified as consisting of three quarks (baryons) or a quark and an antiquark (mesons). Their wave functions remain largely unknown even though the elementary quark and gluon interactions are governed by Quantum Chromodynamics (QCD). I discuss an approach to relativistic bound states based on an expansion in the Planck constant hbar. This allows the derivation of mesons and baryons at the Born level (excluding loop effects), and gives wave functions that have several intriguing properties.

Harmonic morphisms and bicomplex manifolds

When: January 11, 2010 at 14:15
Where: The CP³ meeting room

Harmonic morphisms are map which preserves Laplace’s equation; they can be characterized as harmonic maps which enjoy a partial conformality condition. We use functions of a bicomplex variable to give unified constructions of harmonic morphisms for different signatures. This uses the notion of complex-harmonic morphism between complex-Riemannian manifolds; we show how these are given by bicomplex-holomorphic functions on a bicomplex manifold when the codomain is one-bicomplex dimensional. On the way, we discuss some interesting conformal compactifications of complex-Riemannian manifolds by interpreting them as bicomplex manifolds such as the bicomplex quadric.
