Go Big, Go Left: Pushing the Limits of Liquid Xenon Detectors for Dark Matter Detection

While there is firm astrophysical evidence for dark matter, fundamental properties of the substance, such as its constituent size and mass, remain key open questions in modern physics. Observation of dark matter interactions with Standard Model particles would enable the first constraints on those properties, but, to date, no such interactions have been observed. The xenon Time Projection Chamber (TPC) technology leads searches worldwide for particle dark matter with masses around the proton mass and above. The LUX-ZEPLIN (LZ) experiment is a next-generation dark matter search featuring a 10 tonne xenon TPC that will begin taking data this year. Over its 5 years of operation, LZ expects to improve upon the current dark matter sensitivity by a factor 30 beyond the current best results. In this talk, I will illustrate the powerful features of LZ that enable us to achieve such sensitivity, as well as present HydroX, a novel and promising upgrade path for LZ using hydrogen-doped xenon to probe dark matter particles with masses below the proton mass. Building on the success of LZ and xenon TPCs, HydroX has the potential to lead the field of low mass particle dark matter searches.
