WIMP dark matter within the dark photon portal
Abstract
Abstract We test the dark photon as a portal connecting to the dark sector in the case of Dirac fermion and complex scalar dark matter (DM) with masses up to 1 TeV. Both the dark photon and the Z boson contribute to the DM annihilation and DM–nucleon scattering processes. We derive the lower limits on the dark parameters from thermal relic density. The corresponding spin-independent DM–proton cross sections are compared with the upper bounds set by direct detection. We explore the allowed regions of the dark parameter space that are consistent with these constraints.
