New Thermal Relic Targets for Inelastic Vector-Portal Dark Matter

Patrick J. Fitzpatrick, Hongwan Liu, Tracy R. Slatyer +1

We examine the vector-portal inelastic dark matter (DM) model with DM mass $m_{\chi }$ and dark photon mass $m_{A^{\prime }}$, in the `forbidden dark matter' regime where $1 \lesssim m_{A'}/m_χ\l…
