Description

We present the analytical results of the two-loop amplitudes for hadronic tW
production, focusing on the leading color and light fermion-loop contributions. The cal-
culation of the two-loop integrals is performed using the method of canonical differential
equations. The results have been expressed in terms of multiple polylogarithms and checked
by comparing the infra-red divergences with the predictions from anomalous dimensions.
Combined with the one-loop squared amplitudes we have obtained previously, we obtain
the hard function relevant for a NNLO Monte Carlo calculation.
