Description

We compute the differential and total rate of the semileptonic decay of polarized top quarks t → lvl+b jet + jet at next-to-leading order (NLO) in the QCD coupling with an off-shell intermediate W boson. We present several normalized distributions, in particular those that reflect the t-spin analyzing powers of the lepton, the b-jet and the W+ boson at LO and NLO QCD. (orig.)
