  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.
