Recent excess in Dark Matter Indirect Detection and possible interpretations

If you have a question about this talk, please contact Damien George .

I discuss the possible Dark Matter Interpretation of two recently claimed excesses in cosmic rays which can be originated by interactions of Dark Matter with SM particles. In the first part of the talk I will discuss the gamma-ray excess originating from the galactic Center. It can be accounted by an annihilating WIMP . I will Show, using the complementarity with other DM searches, which Kind of particle Setups are favored, and the prospect of discovery of future experiments, including collider. In the second part I will discuss the detection of a 3.55 KeV photon line from several astrophysical objects and present a simple model of decaying DM which can account for it and can be as well tested in collider searches.

This talk is part of the HEP phenomenology joint Cavendish-DAMTP seminar series.
