Probing of $Wtb$ Anomalous Couplings via the $tW$ Channel of Single Top Production

Abstract

The potential of LHC for investigation of the $W$-$t$-$b$ vertex through the $tW$ channel of single top quark production is studied. Unlike the other two single top quark production processes ($t-$channel and $s-$channel), the $tW$ channel provides the possibility to study the $Wtb$ vertex without receiving contamination from FCNC. This study has been done at parton level but is involved the separation of signal from backgrounds when both $W$-bosons decay to leptons. In this study $\mathcal{C}\mathcal{P}$ is assumed to be conserved. The 68% C.L. bounds on the non-Standard Model couplings are estimated.
