W′ Boson near 2 TeV: Predictions for Run 2 of the LHC

We present a renormalizable theory that includes a W′ boson of mass in the 1.8-2 TeV range, which may explain the excess events reported by the ATLAS Collaboration in a WZ final state, and by the CMS Collaboration in e+e-jj, Wh0, and jj final states. The W′ boson couples to right-handed quarks and leptons, including Dirac neutrinos with TeV-scale masses. This theory predicts a Z′ boson of mass in the 3.4-4.5 TeV range. The cross section times branching fractions for the narrow Z′ dijet and dilepton peaks at the 13 TeV LHC are 10 and 0.6 fb, respectively, for MZ′=3.4 TeV, and an order of magnitude smaller for MZ′=4.5 TeV.
