The thermal-relic mechanism for the production of dark-matter in the early universe, combined with the precision measurements of the cosmic microwave background and the lack QUINCEANERA of observation of dark matter at the LHC, motivates the search for dark matter in the mass range between 1 MeV and 1 GeV.We describe the concept for the Light Dark Matter Experiment (LDMX), which could carry out such a search using the missing-momentum technique.The experiment would utilize a unique high-rate, low-current electron beam with an energy between 4 GeV and 10 GeV, and Flight Socks would have sensitivity to the thermal-relic hypothesis over a wide range of masses below 1 GeV.
