Description
Measurements of single top-quark production cross section in proton proton collisions at 7 and 8 TeV are presented.
In the leading order process, a W boson is exchanged in the t-channel. The single top-quark and anti-top total production
cross sections, their ratio, as well as a measurement of the inclusive production cross section is presented.
Differential cross sections for the top and anti-top processes are measured as a function of the transverse momentum
and the absolute value of the rapidity of top and anti-top, respectively. In addition, a measurement of the
production cross section of a single top quark in association with a W boson is presented. All measurements are
compared to NLO and NLO+NNLO calculations and the CKM matrix element |Vtb| is determined. In addition, the
s-channel production is explored and limits on exotic production in single top quark processes are discussed.
This includes the search for flavor changing neutral currents and the search for additional W’ bosons in the s-channel.
