Abstract

Abstract: A number of LHC resonance search channels display an excess in the invariant mass region of 1.8–2.0 TeV. Among them is a 3.4σ excess in the fully hadronic decay of a pair of Standard Model electroweak gauge bosons, in addition to potential signals in the HW anddijetfinalstates. Weperformamodel-independentcross-sectionfittotheresults of all ATLAS and CMS searches sensitive to these final states. We then interpret these results in the context of the Left-Right Symmetric Model, based on the extended gauge group SU(2)_L × SU(2)_R × U(1)′, and show that a heavy right-handed gauge boson W_R can naturally explain the current measurements with just a single coupling g_R ∼ 0.4. In addition, we discuss a possible connection to dark matter.
