Speaker: Yuanhong Guo(Chinese Academy of Sciences) Abstract: ​In recent years, the bootstrap method has made significant progress in calculating physical quantities in quantum field theories. The main idea of the bootstrap method is to obtain the final result directly by appropriately assuming a general ansatz of the result and utilizing some known physical constraints. The bootstrap method also provides a way to comprehend the maximal transcendentality principle, which claims that the maximally transcendental parts of a class of physical quantities (such as the cusp anomalous dimensions and the loop corrections of the form factors, etc.) are the same in N=4 SYM and QCD. The uniqueness of the results can be understood by the universal physical constraints in different field theories. In this seminar talk, I will present the related progress of bootstrapping the two-loop four-point form factors in the gauge field theories based on the master integrals and demonstrate the maximal transcendentality principle for a series of form factors through the bootstrap strategy.

Speaker: Hjalte Axel Frellesvig(Zhejiang University)  Abstract: The mathematical field of intersection theory has provided an important new perspective on Feynman integrals and the relations between them. With this approach it is possible to derive such relations with a direct projection, providing a promising alternative to the slow standard approach based on IBPs.I will discuss various aspects of this mathematical framework, including newer developments based on relative cohomology which turns out to be a perfect fit for the mathematical structure of Feynman integrals. I will also discuss some brand new developments, that helps bring the day when the intersection-based approach can outcompete IBPs within sight.

Vi sætter punktum for studieåret på IMADA med jordbærkage, vin, vand, øl, snacks og masser af godt sommerhumør 😃!

ReNewQuantum, or 'Recursive and Exact New Quantum Theory,' is based on advanced geometric and topological constructions. This project aims to revolutionize Quantum Theory by developing explicit recursive schemes that effectively compute quantum corrections to all orders and achieve exact results using all non-perturbative contributions. The conference will serve as a platform for sharing groundbreaking research and fostering collaboration among leading experts in the field.
