Top-quark production cross sections at higher perturbative orders
Abstract
I present calculations of higher-order corrections to top-quark production via three different processes: the production of a top-antitop pair and a boson; single-top quark production in the -channel; and top-antitop production with a Higgs boson. It is shown that the contributions from soft-gluon corrections are numerically dominant and large in all these processes. I present approximate NNLO (aNNLO) and approximate NLO (aNLO) cross sections that include soft-gluon corrections added to the exact NLO QCD results. Electroweak corrections through NLO are also included for and production. The theoretical predictions are compared to LHC measurements of total cross sections for these processes.
