2 TeV Higgs boson and diboson excess at the LHC

2 TeV Higgs boson and diboson excess at the LHC

Diboson resonance with mass around 2 TeV in the dijet invariant mass spectrum is reported by ATLAS and CMS experiments in proton–proton collisions at s=8 TeV. We propose that the candidate of resonance is a heavy neutral Higgs H0 or charged Higgs H± and use the extended two-Higgs-doublet (THD) to de...
