Dark matter freeze-in via a kinetically mixed dark photon
We study a model in which dark matter is a Dirac fermion with sub-GeV mass that interacts with the Standard Model via a dark photon, which kinetically mixes with the photon. We use the Boltzmann equation to calculate the relic abundance predicted by freeze-in and find the coupling strength required...
