英文摘要	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 similar to 10(-26) 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.
