Abstract

We present the analytic calculation of the Master Integrals for the two loop, non-planar topologies that enter the calculation of the amplitude for top-quark pair hadroproduction in the quark-annihilation channel. Using the method of differential equa tions, we expand the integrals in powers of the dimensional regulator and determine the expansion coefficients in terms of generalized harmonic polylogarithms of two dimensionless variables through to weight four.
