英文摘要	The resonant excesses around 2 TeV reported by the ATLAS Collaboration can be explained in the left-right model, and the tight constraints from lepton plus missing energy searches can be evaded if the SU(2)(R) gauge symmetry is leptophobic. We, for the first time, propose an anomaly-free leptophobic left-right model with gauge symmetry SU(3)(C) x SU(2)(L) x SU(2)(R) x U(1)(X), where the SM leptons are singlets under SU(2)(R). The gauge anomalies are cancelled by introducing extra vectorlike quarks. The mass of the Z' gauge boson, which cannot be leptophobic, is assumed to be around or above 2.5 TeV so that the constraint on the dilepton final state can be avoided. Moreover, we find that the W' -> WZ channel cannot explain the ATLAS diboson excess due to the tension with the constraint on the W' -> jj decay mode. We solve this problem by considering the mixings between the SM quarks and vectorlike quarks. We show explicitly that the ATLAS diboson excess can be explained in the viable parameter space of our model, which is consistent with all the current experimental constraints.
