Seminarium Kosmologia i Fizyka Cząstek

I will talk about generic dark matter candidates whose genesis are out-of-equilibrium, as contrary to the more popular weakly-interacting (WIMP) scenario. The motivation comes from the absence of WIMP signals in different experimental set-ups, which constrains the relevant couplings to the visible sector to be much smaller than originally thought. Discussion on initial conditions at reheating period will be presented, as well as possible phenomenology of these elusive candidates.
