Abstract
We consider four two-loop three-point vertex diagrams with arbitrary exponents 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 similar calculation in the literature, and our original results are neatly expressed in terms of products of gamma functions.Keywords
