Description
Large mass liquid xenon detectors, such as the imminent LUX-ZEPLIN (LZ) and XENONnT experiments, are leading the search for dark matter particles with masses above ~5 GeV/c^2. HydroX is a new effort to dissolve hydrogen into liquid xenon to allow experiments such as LZ to probe sub-GeV/c^2 dark matter with both spin-dependent and spin-independent couplings. The use of hydrogen-doped xenon takes advantage of the kinematic matching of the light nucleus to dark matter particles with masses down to ~100 MeV, while retaining the excellent self-shielding property of liquid xenon. This talk will give an overview of the use of dissolved hydrogen in liquid xenon for sub-GeV/c^2 dark matter searches and describe ongoing and planned R&D efforts for HydroX.
