Tackling Apparent Singularities in Calabi-Yau Feynman Integrals

Speaker

Sebastian Pögel

Description

It is well-known that Calabi-Yau geometries make a prominent appearance in the evaluation of Feynman integrals. Going beyond the simplest cases of Calabi-Yau integrals—-specifically the Banana integrals—-I will examine features that require extensions of established methods, particularly in the presence of apparent singularities. I will illustrate these methods through the derivation of an epsilon-factorized differential equation for a four-loop integral connected to the 5PM correction in black hole scattering, which is linked to a Calabi-Yau 3-fold geometry.
