Title: Signals of a 2 TeV $W'$ boson and a heavier $Z'$ boson

We construct an SU(2) L x SU(2) R x 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 CMS and ATLAS excess events in the e +e -jj, jj, Wh 0 and WZ channels in terms of a W' boson of mass near 1.9 TeV and of coupling g R in the 0.4-0.5 range (with the lower half preferred by the limits on tb-bar resonances). We found that the production cross section of this W' boson at the 13 TeV LHC is in the 720-1100 fb range, allowing sensitivity in more than 17 final states. Furthermore, we determine that the Z' boson has a mass in the 2.9-4.5 TeV range and several decay channels that can be probed in Run 2 of the LHC, including cascade decays via heavy Higgs bosons. Interpreting the CMS e +e -event at 2.9 TeV as coming from the Z', the mass ratio of the Z' and W' bosons requires g R ≈0.48, which implies a pp →Z' → ℓ +-cross section of 2 fb at √s = 13more » TeV.« less
