    Presentation

    Liquid argon is an excellent target for direct dark matter detection thanks to its scintillation and ionization responses combined with strong pulse-shape discrimination (PSD). The DarkSide-20k experiment, now under construction in the Gran Sasso National Laboratory (LNGS), Italy, will use a liquid argon dual-phase time projection chamber aiming at a background-free search for Weakly...

    Presentation

    The LUX-ZEPLIN (LZ) experiment employs a 7-tonne liquid xenon time projection chamber operating 4850 feet underground at the Sanford Underground Research Facility in Lead, South Dakota, USA. LZ has achieved world-leading sensitivity to WIMP dark matter above 5 GeV/c² and reported the first >3σ evidence of coherent elastic neutrino-nucleus scattering from ⁸B solar neutrinos. The natural 8.9%...

    Presentation

    PandaX-20T is a next-generation liquid xenon detector for rare-event searches, with stringent requirements on radiopurity and background control. We present the ongoing low-background effort for PandaX-20T, including material screening, development of new low-background materials and detector components, krypton assay, radon-related surface contamination control, and detector background...

    Presentation

    DEAP‑3600, with its 3.3‑tonne target and located at SNOLAB, currently represents the leading effort within the international community in the dark‑matter direct detection in liquid argon, while construction of the next‑generation experiment, DarkSide‑20k, is underway at LNGS in Italy. By analyzing approximately three years of data, DEAP‑3600 has recently released its most up-to-date exclusion...

    Presentation

    The LEGEND experiment aims to detect neutrinoless double beta decay (0νββ) of Ge-76 using high-purity germanium (HPGe) detectors immersed in liquid argon (LAr). The LAr serves both as a coolant and as an active shield against background radiation. In the current phase (LEGEND-200), HPGe detectors are operated in conventional atmospheric LAr, which contains the cosmogenically activated...
