On evaluation of two-loop self-energy diagram with three propogator
Abstract
Small momentum expansion of the "sunset" diagram with three different masses is obtained. Coefficients at powers of p2 are evaluated explicitly in terms of dilogarithms and elementary functions. Also some power expansions of "sunset" diagram in terms of different sets of variables are given.
