  A search for heavy, right-handed neutrinos, N[l] (l = e, mu), 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 inverse femtobarns. 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[N]) 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[N])
exclusion region beyond previous results.
