Abstract
Measurements of t-channel single top quark production in proton-proton collisions at the LHC at center-of-mass energies of 7 and 8 TeV, using data collected with the CMS experiment during the years 2011 and 2012, are presented. The analyses consider final states where the W boson from the top quark decays into electron-neutrino or muon-neutrino, and makes use of kinematic characteristics of electroweak single top production for the separation of signal from backgrounds using multivariate methods. The results are compared with the most precise Standard Model theory predictions. Measurements of top/anti-top cross section ratio and of various differential single top quark production cross sections are also presented.
