Search for anomalous Wtb couplings and top FCNC in t-channel single-top-quark events in the CMS experiment

Single-top-quark events in the t-channel are used to probe Wtb anomalous couplings and to search for top-quark Flavor-Changing Neutral Current (FCNC) interactions in proton-proton collisions with the CMS experiment. A Bayesian neural network is used to discriminate between signal and backgrounds. Th...

description Single-top-quark events in the t-channel are used to probe Wtb anomalous couplings and to search for top-quark Flavor-Changing Neutral Current (FCNC) interactions in proton-proton collisions with the CMS experiment. A Bayesian neural network is used to discriminate between signal and backgrounds. The observed event yields are consistent with SM prediction, and exclusion limits at 95\% C.L. are determined.
