This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 sqrt(s) = 7 and 8 TeV correspond to integrated luminosities of 5.0 and 19.7 inverse-femtobarns, respectively. The analysis is performed using events with one muon and two or three jets. A Bayesian neural network technique, used to discriminate between the signal and backgrounds, is found 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
