- 요약This dissertation presents progress towards discovery of physics beyond the Standard Model. Searches for dark matter in the form of weakly interacting massive particles (WIMPs) and a neutrinoless double beta decay search are presented. Both searches utilize the LUX-ZEPLIN (LZ) experiment. World-leading constraints on WIMP dark matter are accomplished with LZ's 7 ton dual-phase liquid/vapor xenon time projection chamber (TPC), in which the author's contributions towards mitigating radon and accidental backgrounds are highlighted. The author additionally led a search for the neutrinoless double beta decay of 160Gd with the LZ Outer Detector.Instrumentation work of novel xenon detector concepts is then presented, with the goal of motivating potential upgrades to the LZ experiment. First, in work involving the crystaLiZe concept, usage of a crystalline/vapor xenon TPC (rather than liquid/vapor) is demonstrated to effectively eliminate radon progeny decays, the dominant background in LZ's WIMP search analysis. A future crystalline/vapor xenon TPC could then potentially be more sensitive to WIMP dark matter compared to liquid/vapor. Next, a measurement of low-energy 4He nuclear recoils in liquid xenon shows such recoils may be identified in a similar manner as xenon nuclear recoils. This result supports the HydroX concept, light-element doping of liquid xenon to gain sensitivity to low-mass WIMP dark matter. In this case, a hydrogen or helium-doped liquid xenon detector would retain discrimination of nuclear recoils and electron recoils. Finally, the characterization of a pathological background in silicon photomultipliers, a potential photodetector for future xenon dark matter experiments, is presented. This instrumentation work lays the foundations for the next-generation of xenon TPC dark matter experiments.
