Sub-GeV dark matter at accelerators with LDMX

This event is part of the HEE Seminar Series.

The program to search for dark matter in the past several of decades has mostly focused on the WIMP (weakly interacting massive particle) 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 discuss the status of this dark matter initiative and focus on the opportunities for dark matter at accelerators including beam dump and fixed target missing momentum techniques. As a specific example, I will go into detail on the missing momentum technique experiment, LDMX, in which I am involved and related spin-offs.
