Abstract

A search for heavy, right-handed neutrinos, (Formula presented.), 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 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 W_R decay width, the region in the two-dimensional (Formula presented.) mass plane excluded at a 95 % confidence level extends to approximately M_WR = 30. 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 (Formula presented.) exclusion region beyond previous results.
