High Energy Physics Seminar

The search for dark matter remains a key focus in modern particle physics. To date, the xenon Time Projection Chamber (TPC) is the leading technology in the search for particle dark matter with masses around the proton mass and above. The LUX-ZEPLIN (LZ) experiment features a 10 tonne dual-phase xenon TPC that expects to improve upon the current dark matter sensitivity by more than an order of magnitude. LZ is now in its commissioning phase and will take data over the next 5 years. In this talk, I will illustrate the powerful features of LZ that enable us to achieve such sensitivity; give an overview of the Liquid Noble Test Facility at SLAC, which played a key role in the development of the LZ TPC; and 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.
