Query: $\gamma$-ray emission signals in the massive graviton mediated dark
  matter model   Dark matter may interact with Standard Model (SM) particle through the
exchange of a massive spin-2 graviton producing signals that can be detected.
In this work we examine the $\gamma$-ray emission signals, including the line
emission and the continuous spectrum component in such a massive
graviton-mediated dark matter model. The constraints of LHC data, dark matter
relic density as well as the dark matter indirect detection data have been
applied to narrow down the parameter space. We focus on the vector dark matter
model which could produce detectable $\gamma$-ray line signal. It is found that
the $\gamma$-ray line data is effective on constraining the model parameters
and the ongoing and upcoming space or ground-based $\gamma$-ray experiments can
constrain the model further.
  As for the continuous $\gamma$-ray emission, the total effective annihilation
cross section is $\sim 10^{-26} {\rm cm^{3}~s^{-1}}$ except at the region where
dark matter mass is around the graviton mass or half of it, which is consistent
with current observational data and will be reliably probed by the upcoming
CTA.
