A model for the LHC diboson excess
Abstract
The first run of the LHC showed hints of a new resonance with mass near 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 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 parameter. We construct variants of a 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 , with mass close to TeV. This is compatible with the intriguing Run 2 observation of a dielectron pair with invariant mass of TeV at CMS.
