Abstract: 

While dark matter constitutes the majority of the matter in the Universe, its potential particle nature is still unknown. Assuming thermal freeze-out in the early Universe, the observed amount of dark matter can be explained by the existence of particles with masses in the MeV - GeV range — if we allow for the existence of a new, low-mass force mediator. The sub-GeV mass range is to date much less explored experimentally than that of heavier thermal relics. It has, however, become a very active area of research over the past decade. One of the most promising experiments to explore this mass range is the Light Dark Matter eXperiment, a fixed-target experiment planned to make use of the 8 GeV electron beam at SLAC. This seminar will review the case for sub-GeV dark matter, introduce the LDMX experiment and give an overview of its current status and future prospects.
