A model for the LHC diboson excess

The first run of the lhc showed hints of a new resonance with mass near 1.9 tev decaying into electroweak gauge boson pairs as well as into dijets. while run 2 has neither confirmed nor ruled out such a resonance, it has yielded new constraints on models attempting to explain these decays. additionally in w′ models where this new resonance is a charged vector boson that is a weak isospin singlet there is the potential for conflict with the electroweak precision t parameter. we construct variants of a w′ resonance model that provide an excellent fit to both run 1 and run 2 data, as well as electroweak precision measurements. the model also predicts a neutral vector boson, a z′, with mass close to 3 tev. this z′ is compatible with the intriguing run 2 observation of a dielectron pair with invariant mass of 2.9 tev at cms.
