Opportunities in Dark Sectors at Accelerators

Room: Sunrise - WH11NE The program to search for dark matter in the past couple of decades has mostly focused on WIMPs at the GeV - TeV scale. It has made impressive strides in sensitivity but has yet to unearth the particle nature of dark matter. Recently there have been many new initiatives to broaden the search for dark matter, many of them smaller scale experiments. One of the main thrusts of this dark matter initiative is to extend searches for dark matter below a GeV using accelerator techniques. I will lay out the various accelerator approaches to look for sub-GeV dark matter including beam dump and fixed target missing momentum techniques. I will detail experimental concepts in which I am involved and discuss their complementarities: LDMX, M^3, and DarkQuest.
