摘要：
We consider a two-loop propagator-type Feynman integral with two composite external vertices as a function of two Bjorken variables x, y, arbitrary indices n(i) of propagators and space-time dimension. The integral is evaluated in terms of a hypergeometric double series. We find a chain of reductions of this double series to simpler functions in some physically interesting situations. The Mellin moments of the integral are also considered.
