Abstract
A search for heavy, right-handed neutrinos, Nℓ ( ℓ=e,μ ), and right-handed W[subscript R] 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[superscript −1]. For models with strict left-right symmetry, and assuming only one N[subscript ℓ] flavor contributes significantly to the W[subscript R] decay width, the region in the two-dimensional (M[subscript WR],M[subscript Nℓ]) mass plane excluded at a 95 % confidence level extends to approximately M[subscript WR]=3.0TeV and covers a large range of neutrino masses below the W[subscript R] boson mass, depending on the value of M[subscript WR]. This search significantly extends the (M[subscript WR],M[subscript Nℓ]) exclusion region beyond previous results.
