Single-top t-channel hadroproduction in the four-flavour scheme with
POWHEG and aMC@NLO    [PDF]

Rikkert Frederix, Emanuele Re, Paolo Torrielli

We present results for the QCD next-to-leading order (NLO) calculation of single-top t-channel production in the 4-flavour scheme, interfaced to Parton Shower (PS) Monte Carlo programs according to the POWHEG and MC@NLO methods. Comparisons between the two methods, as well as with the corresponding process in the 5-flavour scheme are presented. For the first time results for typical kinematic distributions of the spectator-b jet are presented in an NLO+PS approach.
