$O(\alpha_s^2)$ corrections to fully-differential top quark decays

High Energy Physics - Phenomenology 2015-06-12 v2

Abstract

We describe a calculation of the fully-differential decay rate of a top quark to a massless bb-quark and a lepton pair at next-to-next-to-leading order in perturbative QCD. Technical details of the calculation are discussed and selected results for kinematic distributions are shown.
