Title: Semi-Visible Dark Photons

A kinetically mixed dark photon is a broadly-encompassing extension of the Standard Model and can provide an observable portal to dark sectors. In this talk, I will discuss some lamppost models where MeV to few GeV dark photons lead to a dark sector with multiple generations of fermions, with or without dark matter candidates. I will focus on their semi-visible signatures (charged particles + missing energy) at e+e− colliders, fixed target, and neutrino detectors. We find models that can still account for the discrepancy in the muon g-2 and are easily testable in current experiments.
