Description

Sensitivity to detecting sub-GeV dark matter in liquid xenon TPCs has been limited by instrumental backgrounds, namely delayed electron noise. For more than a decade, attempts to mitigate this background have proved inconclusive. In this talk, we will show new data that enlightens the mechanism of delayed electron noise, as well as pathways to its removal. With the assumption that this background can be eliminated, we present sensitivity projections for sub-GeV dark matter candidates, including hidden sector models.
