The twoloop sunrise graph in two spacetime dimensions with arbitrary masses in terms of elliptic dilogarithms
Abstract
We present the twoloop sunrise integral with arbitrary nonzero masses in two spacetime dimensions in terms of elliptic dilogarithms. We find that the structure of the result is as simple and elegant as in the equal mass case, only the arguments of the elliptic dilogarithms are modified. These arguments have a nice geometric interpretation.
