Symmetry Restored in Dibosons at the LHC?
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 excess in the fully hadronic decay of a pair of Standard Model electroweak gauge bosons, in addition to potential signals in the and dijet final states. We perform a model-independent cross-section fit to the results 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 , and show that a heavy right-handed gauge boson can naturally explain the current measurements with just a single coupling . In addition, we discuss a possible connection to dark matter.
