*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 s = 7 $$ \sqrt{s}=7 $$ and 8 TeV correspond to integrated luminosities of 5.0 and 19.7 fb

^{−1}, respectively. The analysis...
