Anomalous Wtb couplings in gamma-proton collision at the LHC

Abstract

We study the possibility for the process $pp\to p\gamma p\to p{W}^{-}t(W^{+}\bar{t})X$ with anomalous Wtb couplings in a model independent effective Lagrangian approach at the LHC. We find 95% confidence level bounds on the anomalous coupling parameters for various values of the integrated luminosity. The improved constraints on the anomalous Wtb couplings have been obtained compared to current limits.
