Interpretations of the ATLAS Diboson Resonances

Understand

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.
