| Abstract: A measurement of the production cross section of single top quarks in the $t$ channel in a fiducial volume using pp collision data collected at a centre-of-mass energy of 8 TeV with the CMS experiment at the LHC is presented. In signal events exactly one muon or electron and two jets, one of which is associated with a b-hadron, are reconstructed. The definition of the fiducial phase space follows closely the constraints imposed by event-selection criteria and detector acceptance. The total fiducial cross section is measured using different generators at next-to-leading order plus parton-shower accuracy, and the differences between the results are discussed. Using as reference aMC@NLO in the four-flavour scheme $\sigma_{t\textrm{-ch}}^{\textrm{fid}}$ is measured to be 3.38 $\pm$ 0.25 (exp.) $\pm$ 0.20 (theo.) pb, in good agreement with the theory predictions. | ||
