Abstract
A search for a heavy right-handed WR boson, and heavy right-handed neutrinos Nl (l = e, μ) performed by the CMS experiment is summarized here. Using the 2.6 fb−1 of integrated luminosity recorded by the CMS experiment in 2015 at a center-of-mass en- ergy of 13 TeV, this search seeks evidence of a WR boson and Nl neutrinos in events with two leptons and two jets. The data do not significantly exceed expected backgrounds, and are consistent with expected results of the Standard Theory given uncertainties. For Standard Theory extensions with strict left-right symmetry, and assuming only one Nl flavor contributes significantly to the WR decay width, mass limits are set in the two-dimensional (MWR , MNl ) plane at 95% confidence level. The limits extend to a WR mass of 3.3 TeV in the electron channel and 3.5 TeV in the muon channel, and span a wide range of Nl masses below MWR .
