Contribution

It introduces NLO QCD corrections to both production and decay processes of single top quarks in the t-channel at various LHC energies, enhancing theoretical precision.

Findings

NLO corrections significantly affect cross section estimates.

Kinematic distributions are refined with NLO effects.

Abstract

We present a study of single top and single antitop quark production in the t-channel mode at the LHC pp collider at 7 TeV, 10 TeV and 14 TeV, including next-to-leading order QCD corrections to the production and decay of the top quark. We discuss the effects of different O(alpha_s) contributions on the inclusive cross section and important kinematic distributions, after imposing the relevant cuts to select t-channel single top quark events.
