Abstract
A search for a heavy right-handed W boson (WR) decaying to a heavy righthanded neutrino and a charged lepton in events with two same- avor leptons (e or ) 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 fb1. No signi cant excess above the standard model expectation is seen in the invariant mass distribution of the dilepton plus dijet system. Assuming t ...
A search for a heavy right-handed W boson (WR) decaying to a heavy righthanded neutrino and a charged lepton in events with two same- avor leptons (e or ) 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 fb1. No signi cant 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 avor NR contributes signi cantly to the WR decay width, the region in the two-dimensional (mWR, mNR) mass plane excluded at 95% con dence level extends to approximately mWR = 4:4TeV 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. ...
