Abstract

With the advent of the LHC, it is important to devise clear tests for physics beyond the standard model. Such physics could manifest itself in the form of new charged bosons, whose presence is most naturally occurring in left-right symmetric models. We analyze the single W-R boson production in an asymmetric left-right model, where the left and right quark mixing matrices are not constrained to be equal. We investigate the cross sections as well as branching ratios of W-R bosons at the LHC, including constraints from low energy phenomenology. We then look for most likely signals in pp -> W(R)t -> t(dijet) production. Including the background, we find that the LHC could show significant signals for the new charged bosons. We compare our results throughout with the manifest left-right symmetric model and comment on similarities and differences.
