Abstract
We consider four two-loop three-point vertex diagrams with arbitrary e xponents of propagators and dimension, three of them with two legs on- shell and one with all legs off-shell. As far as we know there is no s imilar calculation in the Literature, and our original results are nea tly expressed in terms of products of gamma functions.
