Probing of $Wtb$ Anomalous Couplings via Single Top Production Processes at the LHC

Dr. Mojtaba Mohammadi Najafabadi from IPM

 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 $\mathcal{CP}$ is assumed to be conserved. The 68% C.L. bounds on the nonStandard Model couplings are estimated.
