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