Garchinger Maier-Leibnitz-Kolloquium: Insights from Calabi-Yau Geometries for Feynman Integrals

by Dr Christoph Nega (Physik-Department T31, TUM)

Thursday 9 Nov 2023, 16:15 → 17:15 Europe/Berlin

Lecture Hall, ground floor (west) (LMU building, Am Coulombwall 1, Campus Garching)

In this talk I want to show how insights from Calabi-Yau geometries can be used to compute Feynman integrals. I will start with an introduction how one nowadays computes amplitudes and Feynman integrals, and where Calabi-Yau varieties show up in this endeavor. After having introduced the basic mathematical concepts of Calabi-Yau varieties, I will discuss different aspects where these insights make the computation of Feynman integrals possible, for instance in the description of the function spaces, boundary conditions and the epsilon expansion of loop integrals in dimensional regularization.
