Interpreting a 2 TeV resonance in WW scattering

A diboson excess has been observed albeit with very limited statistical significance in WW, WZ, and ZZ final states at the LHC experiments using the accumulated 8 TeV data. Assuming that these signals are due to resonances resulting from an extended symmetry breaking sector in the standard model and...
