Abstract: The hints from the LHC for the existence of a W′ boson of mass around 1.9 TeV point towards a certain SU(2)L × SU(2)R × U(1)B−L gauge theory with an extended Higgs sector. We show that the decays of the W′ boson into heavy Higgs bosons have sizable branching fractions. Interpreting the ATLAS excess events in the search for same-sign lepton pairs plus b jets as arising from W′ cascade decays, we estimate that the masses of the heavy Higgs bosons are in the 400-700 GeV range.
