Abstract

We construct an SU(2)L×SU(2)R×U(1)BLSU(2)_L\times SU(2)_R\times U(1)_{B-L} model with a Higgs sector that consists of a bidoublet and a doublet, and with a right-handed neutrino sector that includes one Dirac fermion and one Majorana fermion. This model explains the Run 1 CMS and ATLAS excess events in the e+ejje^+e^-jj, jjjj, Wh0Wh^0 and WZWZ channels in terms of a WW' boson of mass near 1.9 TeV and of coupling gRg_R in the 0.4--0.5 range, with the lower half preferred by limits on tbˉt \bar b resonances and Run 2 results. The production cross section of this WW' boson at the 13 TeV LHC is in the 700--900 fb range, allowing sensitivity in more than 17 final states. We determine that the ZZ' boson has a mass in the 3.4--4.5 TeV range and several decay channels that can be probed in Run 2 of the LHC, including cascade decays via heavy Higgs bosons.
