Abstract:
We point out that the discovery of a right-handed charged gauge boson W±R 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 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 (2.5σ 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 B−L violating interactions e±RW∓R→e∓RW±R. Our conclusions are very general in the sense that they do not necessarily demand for a lepton number violating detection signal of W±R.
