$\mathcal O(α_s^2)$ corrections to fully-differential top quark
decays    [PDF]

Mathias Brucherseifer, Fabrizio Caola, Kirill Melnikov

We describe a calculation of the fully-differential decay rate of a top quark to a massless $b$-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.
