FI: TOWARDS IMPROVED OVERCLOSURE BOUNDS FOR WIMP-LIKE DARK MATTER MODELS 
 ELENCO COMPLETO

SEZIONE DI FIRENZE
Dr. Simone Biondini (Albert Einstein Center, Institute for Theoretical Physics - Uni Bern) Tight constraints from the LHC and from direct and indirect detection experiments have put many simple dark matter models under tension in recent years. This calls for new ideas in model building, but perhaps also for new precision in the computations on which a given dark matter scenario is based. In particular, we focus on the calculation of the dark matter relic density via thermal freeze-out and investigate the impact of the thermal medium: modified Sommerfeld effect, Salpeter correction, decohering scatterings, formation and dissociation of bound states. We apply this formalism to a model with Majorana fermion dark matter co-annihilating with a strongly interacting scalar
