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-+/- and U-+/-+/- by the reduced minimal 331 model to the Higgs decay channels h -> gamma gamma and Z gamma. Our numerical results show that the vector bileptons can enhance the partial width Gamma(h -> gamma gamma), while reduce the partial width Gamma(h -> Z gamma), which are anti-correlated. With reasonable values of the relevant free parameters, the vector bileptons can explain the LHC data for the gamma gamma signal. If the CMS data persists, the values of the free parameters lambda(2) and lambda(3) should be severe constrained. (C) 2013 Elsevier B.V. All rights reserved.
