Symmetry restored in dibosons at the LHC?
- Mr. Johann BREHMER
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 3.4 sigma excess in the fully hadronic decay of a pair of Standard Model electroweak gauge bosons, in addition to potential signals in the HW and dijet final states. We present 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 a Left-Right Symmetric Model, and show that a heavy right-handed gauge boson W_R can naturally explain the current measurements with just a single coupling gR ~ 0.4.
