TL;DR

This paper explores potential interpretations of ATLAS diboson resonance signals around 2 TeV, proposing a leptophobic vector boson as a plausible explanation consistent with current experimental constraints.

Contribution

It introduces the leptophobic vector boson as a new interpretation for the ATLAS diboson excess, analyzing its compatibility with existing collider and precision measurements.

Findings

Leptophobic vector boson can explain the diboson excess

The proposed model aligns with current LHC constraints

The resonance suggests new physics at the TeV scale

Abstract

The ATLAS collaboration has reported excesses in searches for resonant diboson production decaying into hadronic final states. This deviation from the Standard Model prediction may be a signature of an extra bosonic particle having a mass of around 2 TeV with a fairly narrow width, which implies the presence of a new perturbative theory at the TeV scale. In this paper, we study interpretations of the signal and its implication to physics beyond the Standard Model. We find that the resonance could be regarded as a leptophobic vector particle, which could explain a part of the observed excesses without conflict with the present constraints from other direct searches for heavy vector bosons at the LHC as well as the electroweak precision measurements.
