This study presents a search for a right-handed W boson (W-R) and a heavy neutrino (N) using data from the CMS experiment at the CERN LHC. No significant excess over the standard model background expectations is observed, providing the most stringent limits on the WR mass to date.
A search is presented for a right-handed W boson (W-R) and a heavy neutrino (N), in a final state consisting of two same-flavor leptons (ee or mu mu) and two quarks. The search is performed with the CMS experiment at the CERN LHC using a data sample of proton-proton collisions at a center-of-mass energy of 13TeV corresponding to an integrated luminosity of 138 fb(-1). The search covers two regions of phase space, one where the decay products of the heavy neutrino are merged into a single large-area jet, and one where the decay products are well separated. The expected signal is characterized by an excess in the invariant mass distribution of the final-state objects. No significant excess over the standard model background expectations is observed. The observations are interpreted as upper limits on the product of W-R production cross sections and branching fractions assuming that couplings are identical to those of the standard model W boson. For N masses m(N) equal to half the W-R mass m(WR) (m(N) = 0.2TeV), mW(R) is excluded at 95% confidence level up to 4.7 (4.8) and 5.0 (5.4) TeV for the electron and muon channels, respectively. This analysis provides the most stringent limits on the WR mass to date.
