Description
Measurements of single top-quark production 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. 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 state-of-the-art theoretical 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 or a search
for monotops.
