Abstract

We point out that the discovery of a right-handed charged gauge boson WR±W_R^\pm with mass of around a few TeV, for example through a signal of two leptons and two jets that has been reported by CMS to have a 2.8σ\sigma local excess or through a signal of a resonance decaying into a pair of standard model (SM) gauge bosons showing a local excess of 3.4σ\sigma (2.5σ\sigma global) reported by ATLAS search, will rule out all possibilities of leptogenesis in all classes of the left-right symmetric extensions of the Standard Model (LRSM) with both triplet and doublet Higgs scalars due to the unavoidable fast gauge mediated BLB-L violating interactions eR±WReRWR±e_{R}^{\pm} W_{R}^{\mp} \rightarrow e_{R}^{\mp} W_{R}^{\pm}. Our conclusions are very general in the sense that they do not necessarily demand for a lepton number violating detection signal of WR±W_R^\pm.
