Title: Heavy vector partners of the light composite Higgs

If the Higgs boson H(125)is a composite due to new strong interactions at high energy, it has spin-one partners, ρH and aH, analogous to the ρand a1 mesons of QCD. These bosons are heavy, their mass determined by the strong interaction scale. The strongly interacting particles light enough for ρH and aH to decay to are the longitudinal weak bosons VL = WL, ZL and the Higgs boson H. These decay signatures are consistent with resonant diboson excesses recently reported near 2TeVby ATLAS and CMS. We calculate σ × BR(ρH → VV) = few fb and σ × BR(aH → VH) = 0.5–1fb at √s = 8TeV, increasing by a factor of 5–7 at 13TeV. As a result, other tests of the hypothesis of the strong-interaction nature of the diboson resonances are suggested.
