Description
In this talk, I will discuss an approach to derive epsilon-factorized differential equations for Feynman integrals. This approach is based on minimal information, namely the choice of a seed integral and an appropriate Ansatz for the differential equation. Previously developed for simple Calabi-Yau integrals, I will show how to deal with complications arising in integrals in physical applications, particularly the appearance of apparent singularities in the Picard-Fuchs operator of the seed integral. I will demonstrate this approach on the example of a four-loop Calabi-Yau integral appearing in the scattering of black holes.
