摘要：

A 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 the sunset diagram in terms of different sets of variables are given. © 1994 The American Physical Society.
