Abstract

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.
