Title: Chasing Shadows: Illuminating the Path from LZ to the Next Generation Dual-Phase Xe TPC Observatory for Dark Matter
Abstract: The nature of dark matter remains one of the most significant unsolved challenges in modern physics. Liquid xenon time projection chambers (LXe-TPCs) have emerged as a powerful tool in the search for WIMP dark matter candidates (Weakly Interacting Massive Particles), particularly in the GeV/c2 range. The XENON-LUX-ZEPLIN-DARWIN (XLZD) collaboration embodies the collective knowledge & expertise of generations of LXe-TPC-based experiments, combining three current world-leading experimental and R&D efforts operating at sub-10-tonne Xe target masses. This talk will present the case for XLZD’s next-generation dual phase xenon observatory for dark matter and neutrino physics, with the capability to explore the WIMP parameter space down to the so-called neutrino fog, a background-limited region where neutrino and WIMP signatures look very similar. A discussion of the lessons learned from the operation & analysis chain for the LUX-ZEPLIN experiment will feature, to motivate the design approach for this detector, as well as an overview of novel detector design concepts and exciting current R&D experiments which may both improve sensitivities to low-mass dark matter models and revolutionise the current dark matter direct detection landscape.
