Production of Purely Gravitational Vector Dark Matter

We explore a possibility of dark matter (DM) interacting with the visible sector only through gravity. We consider the case of the vector DM
and discuss both perturbative and non-perturbative mechanisms that can
be relevant for DM production. In the first case, we investigate particle
production during reheating phase via the freeze-in mechanism, while the
latter refers to the particle creation in the time-varying background during
inflation. In each case, we find a viable range in parameter space which
reproduces the observed DM relic abundance.
