On a two-loop crossed six-line master integral with two massive lines

Huber, T.

Understand

We compute the two-loop crossed six-line vertex master integral with two massive lines in dimensional regularisation, and give the result up to the finite part in D-4.

We focus in particular on the purely analytical calculation of the boundary condition which we derive from a three-fold Mellin-Barnes representation.
We also describe how the computation of the boundary condition is used to derive three non-trivial relations among harmonic polylogarithms of the sixth root of unity.
