LHC diboson excesses as an evidence for a heavy WW resonance

Abstract

Recently reported diboson excesses at LHC are interpreted to be connected with heavy $WW$ resonance with weak isotopic spin 2. The resonance appears due to the wouldbe anomalous triple interaction of the weak bosons, which is defined by well-known coupling constant $\lambda$. We obtain estimates for the effect, which qualitatively agree with ATLAS data. Effects are predicted in inclusive production of $W^{+}{W}^{+},W^{+}(Z,\gamma ),W^{+}{W}^{-},(Z,\gamma )(Z,\gamma ),W^{-}(Z,\gamma ),W^{-}{W}^{-}$ resonances with $M_R\simeq 2TeV$, which could be reliably checked at the upgraded LHC with $\sqrt{s}=13TeV$. In the framework of an approach to the spontaneous generation of of the triple anomalous interaction its coupling constant is estimated to be $\lambda =-0.017\pm 0.005$ in an agreement with existing restrictions.
