Short-lived mediators are often used to describe dark matter interactions with Standard Model particles. When the dark matter mass is heavier than the mass of the mediator, it may self-annihilate into short-lived mediators, and in some cases this mig

International audience; We investigate the feasibility of gaseous TPC as a telescope and a polarimeter for cosmic gamma-rays, focussing on the energy range from 1 to 100 MeV. Our beam results show the angular resolution can reach a factor of 2 better

Dirac fermion dark matter models with heavy $Z^{\prime}$ mediators are subject to stringent constraints from spin-independent direct searches and from LHC bounds, cornering them to live near the $Z^{\prime}$ resonance. Such constraints can be relaxed
