A novel search strategy for right-handed charged gauge bosons at the Large Hadron Collider

Abstract

Abstract We explore the potential of the Large Hadron Collider (LHC) in detecting a signal originating from the production of a heavy SU(2)R charged gauge boson that then decays into a top-bottom quark pair via the mediation of a right-handed neutrino, pp → WR → NRℓ → (ℓ′tb)ℓ. Such a channel, that we study in the context of the minimal Left-Right Symmetric Model, contrasts with conventional smoking-gun signatures targeted experimentally and phenomenologically in which only light quarks are involved. We propose a selection strategy aimed at extracting such a top-bottom signal and we estimate the resulting sensitivity of the LHC to the model. Our results demonstrate the potential impact of such a search and we therefore urge the experimental collaborations to carry out a similar analysis in the light of present and future data.
