Abstract: The gravitational evidence for the existence of dark matter is overwhelming; observations of galactic rotation curves, the CMB power spectrum, and light element abundances independently suggest that over 80% of all matter is "dark" and beyond the scope of the Standard Model. However, its particle nature is currently unknown, so discovering its potential non-gravitational interactions is a major priority in fundamental physics. In this talk, I will survey the existing dark matter search effort and introduce an emerging field of fixed-target searches that are poised to cover hitherto unexplored dark matter candidates with MeV-GeV masses. Exploring this mass range is essential for fully testing a broad class of theories in which dark matter abundance arises from dark-visible interactions in thermal equilibrium in the early universe.
