| Özet |
| Single top quark events produced in the t channel are used to set limits on anomalous Wtb couplings and to search for top quark flavour-changing neutral current (FCNC) interactions. The data taken with the CMS detector at the LHC in proton-proton collisions at and 8 TeV correspond to integrated luminosities of 5.0 and 19.7 fb− 1, respectively. The analysis is performed using events with one muon and two or three jets. A Bayesian neural network technique is used to discriminate between the signal and backgrounds, which are observed to be consistent with the standard model prediction. The 95% confidence level (CL) exclusion limits on anomalous right-handed vector, and left-and right-handed tensor Wtb couplings are measured to be| f R V|< 0.16,| f L T|< 0.057, and− 0.049< f R T< 0.048, respectively. For the FCNC couplings κ tug and κ tcg, the 95% CL upper limits on coupling strengths are| κ tug|/Λ< 4.1 … |
