| Abstract: A search for heavy, right-handed neutrinos, Nℓ (ℓ = e, μ), and right-handed WR bosons, which arise in the left-right symmetric extensions of the standard model, has been performed by the CMS experiment. The search was based on a sample of two lepton plus two jet events collected in proton-proton collisions at a center-of-mass energy of 8 TeV corresponding to an integrated luminosity of 19.7 fb−1. No significant excess of events over the standard model expectation is observed. For models with strict left-right symmetry, and assuming only one Nℓ flavor contributes significantly to the WR decay width, the region in the two-dimensional (M(WR), M(Nℓ)) mass plane excluded at a 95% confidence level extends to approximately M(WR) = 3.0 TeV and covers a large range of neutrino masses below the WR boson mass, depending on the value of M(WR). This search significantly extends the (M(WR), M(Nℓ)) exclusion region beyond previous results. | ||
