If the Higgs boson H(125)is a composite due to new strong interactions at high energy, it has spin-one partners, ρ_H and a_H, 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 ρ_H and a_H to decay to are the longitudinal weak bosons V_L = W_L, Z_L 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(ρ_H → VV) = few fb and σ × BR(a_H →more » 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.« less
