Z′-mediated dark matter with low-temperature reheating

Abstract We consider a simple extension of the standard model with fermionic dark matter (DM) and a Z′ gauge boson acting as a mediator. We also assume a scenario where cosmic reheating occurs at low temperatures due to the decay of a massive inflaton into standard model states. To follow the evolut...
