Search for New Physics via Low-Energy Electron Recoils with a 4.2 Tonne-Year Exposure from the LZ Experiment

D. S. Akerib, A. K. Al Musalhi, F. Alder, J. Almquist et autres

We report results from searches for new physics models through electron recoils using data collected by the LUX-ZEPLIN experiment during its first two science runs, with a total exposure of 4.2 tonne-years. The observed data are consistent with a background-only hypothesis. Constraints …

Energy Calibration and Performance of HPGe Detectors in the LEGEND-200 Experiment

The LEGEND Collaboration, H. Acharya, M. Agostini, A. Alexander et autres

This paper describes the energy scale procedures and germanium detectors performance in the LEGEND-200 experiment, a critical component for the first unblinding in the search for neutrinoless double beta decay. We detail the digital signal processing pipeline, the methodologies for peak-shape modeling …

Low-Energy Radon Backgrounds from Electrode Grids in Dual-Phase Xenon TPCs

D. S. Akerib, A. K. Al Musalhi, F. Alder, B. J. Almquist et autres

The dual-phase xenon time projection chamber (TPC) is a powerful technology to detect rare interactions such as scatters of dark matter particles on nuclei. In particular, the built-in gain of ionization signals in a dual-phase TPC makes it sensitive to events in …

First Results on the Search for Lepton Number Violating Neutrinoless Double-β Decay with the LEGEND-200 Experiment

H. Acharya, N. Ackermann, M. Agostini, A. Alexander et autres

The LEGEND Collaboration is searching for neutrinoless double-beta (0v⁢ß⁢ß ) decay by operating high-purity germanium detectors enriched in 76Ge in a low-background liquid argon environment. Building on key technological innovations from the GERmanium Detector Array (GERDA) experiment and the MAJORANA DEMONSTRATOR experiment, …
