Picard-Fuchs equations for Feynman integrals
Stefan Müller-Stach, Stefan Weinzierl, Raphael Zayadeh
We present a systematic method to derive an ordinary differential equation for any Feynman integral, where the differentiation is with respect to an external variable. The resultin…

A second-order differential equation for the two-loop sunrise graph with arbitrary masses
Stefan Müller-Stach, Stefan Weinzierl, Raphael Zayadeh
We derive a second-order differential equation for the two-loop sunrise graph in two dimensions with arbitrary masses. The differential equation is obtained by viewing the Feynman…
