Abstract: I give a brief overview of the claim of a gamma-ray line in the Fermi-LAT data, and its possible explanation in term of dark matter models. In the last part of the talk, I focus on the possibility that gamma-ray lines from dark matter annihilation may come with gluon-lines, and discuss the phenomenological consequences and the experimental constraints on such a scenario. |
