N2 - A search for heavy, right-handed neutrinos, (Formula presented.), 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 8TeV corresponding to an integrated luminosity of 19.7 fb-1. For models with strict left-right symmetry, and assuming only one (Formula presented.) flavor contributes significantly to the WR decay width, the region in the two-dimensional (Formula presented.) mass plane excluded at a 95 % confidence level extends to approximately MWR = 30. TeV and covers a large range of neutrino masses below the WR boson mass, depending on the value of MWR. This search significantly extends the (Formula presented.) exclusion region beyond previous results.
