【 摘 要 】

A search for heavy, right-handed neutrinos, N(sup l) (l=e, mu), and right-handed W(sup 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 (sub -1). No significant excess of events over the standard model expectation is observed. For models with strict left-right symmetry, and assuming only one N(sup l) flavor contributes significantly to the W(sup R) decay width, the region in the two-dimensional (M(sup WR1)M(sup Nl)) exclusion region beyond previous results.
