Sommaire:

In this seminar I will present the SloopS code and some of its applications to the computation of the DM relic density at one-loop level in the Minimal Supersymmetric Standard Model (MSSM). The complete renormalization needed for the computation will be presented and some particular quantum effects affecting the self-annihilation, which are absent at LO, will be scrutinized. I will also discuss the interpretation of the recently claimed gamma-ray line signal found in the FERMI data as coming from DM annihilation, in the framework of the Next-to-Minimal Supersymmetric Model (NMSSM). A particular attention will be paid in considering the interplay between DM searches and the LHC to investigate the SUSY origin of the signal.
