LHC diboson excesses as an evidence for a heavy WW resonance

TL;DR

This paper interprets LHC diboson excesses as evidence for a heavy WW resonance caused by anomalous triple weak boson interactions, predicting observable effects at 13 TeV LHC and estimating the interaction coupling constant.

Contribution

It introduces a novel interpretation of diboson excesses as a heavy WW resonance from anomalous interactions, providing estimates consistent with experimental data.

Findings

Qualitative agreement with ATLAS data.

Predicted resonance effects at 13 TeV LHC.

Estimated anomalous coupling constant λ = -0.017 ± 0.005.

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 $M_R \simeq 2\,TeV$, which could be reliably checked at the upgraded LHC with $\sqrt{s}\,=\,13 TeV$. 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.
