22 Jul 2013 | | Abstract: | Takeing into account of the constraints on the relevant parameters from the
muon anomalous magnetic moment, we consider the contributions of the vector
bileptons $V^{pm}$ and $U^{pmpm}$ predicted by the reduced minimal 331 model
to the Higgs decay channels $h
ightarrow gamma gamma$ and $Zgamma$. Our
numerical results show that the vector bileptons can enhance the partial width
$Gamma(h
ightarrow gammagamma)$, while reduce the partial width
$Gamma(h
ightarrow Zgamma)$, which are anti-correlated. With reasonable
values of the relevant free parameters, the vector bileptons can explain the
$LHC$ data for the $gammagamma$ signal. If the $CMS$ data persists, the value
of the free parameters $ lambda_{2}$ and $ lambda_{3}$ should be severe
constrained. | | Source: | arXiv, 1307.5572 | | Services: | Forum | Review | PDF | Favorites | |
