Collider signatures of WR boson in the alternative left-right model

Abstract

Alternative Left-Right Models offer an attractive option to left-right models. Emerging from E6 grand unification, these models are consistent with light scalars which do not induce flavour-changing neutral currents due to the presence of exotic quarks. Here we investigate the signature at the LHC collider of the charged WR boson, which can be lighter than in left-right models. We include constraints from collider data and show that WR can be produced in pairs, or in conjunction with a light charged Higgs boson. The final decay products involve leptons or jets. We explore all production and decay possibilities and indicate which ones are most promising to be observed at the colliders. Our analysis shows that signals of WR bosons can be observed at the LHC at 27 TeV, some for lower luminosity, and under most favourable conditions, even at 13 TeV.
