Serpico at PPC-CERN: “Theoretical aspects of dark matter indirect detection”

“Dark Matter (DM) was already discovered indirectly: via gravity. But gravity is “universal” and does not permit particle identification: a discovery via electromagnetic, strong or weak probes is needed. The LHC at CERN was designed to study the electroweak (EW) scale, however there is no astrophysical or cosmological evidence whatsoever for the EW scale being the right one for explaining the DM problem. In fact, there is no evidence that the astrophysical DM is made of particles. The logic has always been the opposite: since the EW scale can be motivated by particle physics, then it might offer “natural” candidates for the DM problem while being accessible to a multi-disciplinary strategy. In the “golden age” for direct searches and colliders, it’s advisable to go back to the “standard practice”: experiments must guide us to Beyond Standard Model (BSM) physics, following the good old pipeline: Particle Physics progress → Theory Framework → Prediction for indirect, allowing a priori searches.” Extracts from Pasquale D. Serpico, “Dark Matter Indirect Detection (theoretical aspects),” PPC 2011 CERN -14 June 2011.
