Progress Towards Two-loop QCD Corrections to pp tt j
Abstract
We present the status of on-going efforts to compute the two-loop virtual corrections to pp tt j in the leading colour approximation. We review the recent study of the master integrals and their differential equations and present some ideas on modern techniques that can be applied to provide complete evaluation of helicity amplitudes containing information on top quark decays in the narrow width approximation.
