Decays of polarized top quarks to lepton, neutrino and jets at NLO QCD

W. Bernreuther, P. González, C. Mellein

We compute the differential and total rate of the semileptonic decay of polarized top-quarks $t\to \ell {\nu }_{\ell }+b\mathrm{jet}+\mathrm{jet}$ at next-to-leading order (NLO) in the QCD c…
