Query: 130 GeV gamma-ray line and enhancement of $h\to\gamma\gamma$ in the
  Higgs triplet model plus a scalar dark matter   With a discrete $Z_2$ symmetry being imposed, we introduce a real singlet
scalar $S$ to the Higgs triplet model with the motivation of explaining the
tentative evidence for a spectral feature at $E_\gamma$ = 130 GeV in the Fermi
LAT data. The model can naturally satisfy the experimental constraints of the
dark matter relic density and direct detection data from Xenon100. The doubly
charged and one charged scalars can enhance the annihilation cross section of
$SS\to\gamma\gamma$ via the one-loop contributions, and give the negligible
contributions to the relic density. $<\sigmav>_{SS\to\gamma\gamma}$ for
$m_{S}=130$ GeV can reach $\ord(1)\times10^{-27} cm^3 s^{-1}$ for the small
charged scalar masses and the coupling constant of larger than 1. Besides, this
model also predict a second photon peak at 114 GeV from the annihilation
$SS\to\gamma Z$, and the cross section is approximately 0.76 times that of
$SS\to\gamma \gamma$, which is below the upper limit reported by Fermi LAT.
Finally, the light charged scalars can enhance LHC diphoton Higgs rate, and
make it to be consistent with the experimental data reported by ATLAS and CMS.
