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

Brucherseifer, Mathias, Caola, Fabrizio, Melnikov, Kirill

Understand

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.
