| 摘要: | 摘要： A search for heavy, right-handed neutrinos, N ℓ ( ℓ = e , μ ), 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 W R decay width, the region in the two-dimensional ( M W R , M N ℓ ) mass plane excluded at a 95 % confidence level extends to approximately M W R = 3.0 TeV and covers a large range of neutrino masses below the W R boson mass, depending on the value of M W R . This search significantly extends the ( M W R , M N ℓ ) exclusion region beyond previous results.
