Abstract: A search for heavy, right-handed neutrinos, N-l (l = e, mu), and right-handed W-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(-1). For models with strict left-right symmetry, and assuming only one N-l 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 W-R boson mass, depending on the value of M-WR. This search significantly extends the (M-WR, M-Nl) exclusion region beyond previous results.
