Vector bileptons and the decays h→γγ,Zγh→γγ,Zγ

Taking into account of the constraints on the relevant parameters from the muon anomalous magnetic moment, we consider the contributions of the vector bileptons V±V± and U±±U±± predicted by the reduced minimal 331 model to the Higgs decay channels h→γγh→γγ and Zγ  . Our numerical results show that the vector bileptons can enhance the partial width Γ(h→γγ)Γ(h→γγ), while reduce the partial width Γ(h→Zγ)Γ(h→Zγ), which are anti-correlated. With reasonable values of the relevant free parameters, the vector bileptons can explain the LHC data for the γγ   signal. If the CMS data persists, the values of the free parameters λ2λ2 and λ3λ3 should be severe constrained.
