On a possibility of a consistent interpretation of diboson excesses at LHC

Abstract

Recently reported diboson and diphoton excesses at LHC are interpreted to be connected with heavy WW zero spin resonances. The resonances appears due to the would-be anomalous triple interaction of the weak bosons, which is defined by well-known coupling constant [Formula: see text]. The 2 TeV anomaly, tentatively corresponds to weak isotopic spin-2 scalar state and the [Formula: see text] 750 GeV anomaly corresponds to weak isotopic spin-0 pseudoscalar state. We obtain estimates for the effect, which qualitatively agree with ATLAS data. Effects are predicted in a production of W[Formula: see text] W[Formula: see text], (Z, [Formula: see text])(Z, [Formula: see text]) via resonance [Formula: see text] with [Formula: see text] 750 GeV, which could be reliably checked at the upgraded LHC at [Formula: see text] 13 TeV. In the framework of an approach to the spontaneous generation of the triple anomalous interaction its coupling constant is estimated to be [Formula: see text] in an agreement with existing restrictions. Specific predictions of the hypothesis are significant effects in decay channels [Formula: see text], [Formula: see text].
