Theoretical results for top-pair and top+W production

Abstract

I present theoretical results for top-pair production as well as for the associated production of top quarks with W bosons. Soft-gluon corrections from resummation are calculated through approximate N3LO and added to fixed-order QCD results, and electroweak corrections are included at NLO. Top-quark transverse-momentum and rapidity distributions are also presented. In all cases the higher-order corrections are large, they reduce the scale dependence, and they improve agreement with recent data.
