Predictions at NNLO of single top-quark production cross sections

Introduction

On this page the LHC Top WG provides predictions at next-to-next-to leading order (NNLO) of total cross sections for the production on a single top-quark in the three different production channels, t-channel, tW channel and s-channel. These cross section are meant to be used as a common reference for normalizing the predictions of single top-quark event yields in analyses performed by the ATLAS and CMS collaborations.

Predictions at 7, 8, 13, 13.6 and 14 TeV for top quark, top antiquark and the combined case

Single-top t channel cross sections

The cross sections of t-channel single top-quark production have been calculated with the MCFM program. The renormalisation and factorisation scales, muR and muF, are taken as dynamic scales given by muR = muF =

The values in the tables are given in pb.
