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…
From motives to differential equations for loop integrals
S. Müller-Stach, S. Weinzierl, R. Zayadeh
In this talk we discuss how ideas from the theory of mixed Hodge structures can be used to find differential equations for Feynman integrals. In particular we discuss the two-loop…
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…
