Description
A search for a heavy right-handed W boson (WR) decaying to a
heavy right-handed neutrino and a charged lepton in events with two
same-flavor leptons (e or μ) and two jets, is presented. The analysis
is based on proton-proton collision data, collected by the CMS
Collaboration at the LHC in 2016 and corresponding to an integrated
luminosity of 35.9 fb-1. No significant excess above the
standard model expectation is seen in the invariant mass distribution of
the dilepton plus dijet system. Assuming that couplings are identical to
those of the standard model, and that only one heavy neutrino flavor
NR contributes significantly to the WR decay
width, the region in the two-dimensional
({m}_{{W}R},{m}_{{N}R}) mass plane excluded at 95%
confidence level extends to approximately {m}_{{W}R}=4.4 TeV
and covers a large range of right-handed neutrino masses below the
WR boson mass. This analysis provides the most stringent
limits on the WR mass to date. [Figure not available: see
