Abstract
The cross section for the production of single top quarks in the t channel is measured in proton–proton collisions at 13TeV with the CMS detector at the LHC. The analyzed data correspond to an integrated luminosity of 2.2fb −1 . The event selection requires one muon and two jets where one of the jets is identified as originating from a bottom quark. Several kinematic variables are then combined into a multivariate discriminator to distinguish signal from background events. A fit to the distribution of the discriminating variable yields a total cross section of 238±13(stat)±29(syst) pb and a ratio of top quark and top antiquark production of R t-ch. =1.81±0.18(stat)±0.15(syst). From the total cross section the absolute value of the CKM matrix element V tb is calculated to be 1.05±0.07(exp)±0.02(theo). All results are in agreement with the standard model predictions.
