Energy Calibration and Performance of HPGe Detectors in the LEGEND-200 Experiment
The LEGEND Collaboration, H. Acharya, M. Agostini +259
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 n…
Model-independent searches of new physics in DARWIN with a semi-supervised deep learning pipeline
J. Aalbers, K. Abe, M. Adrover +231
We present a novel deep learning pipeline to perform a model-independent, likelihood-free search for anomalous (i.e., non-background) events in the proposed next generation multi-t…
Transformer-Based Pulse Shape Discrimination in HPGe Detectors with Masked Autoencoder Pre-training
Marta Babicz, Saúl Alonso-Monsalve, Alain Fauquex +1
Pulse-shape discrimination (PSD) in high-purity germanium (HPGe) detectors is central to rare-event searches such as neutrinoless double-beta decay (0vBB), yet conventional approac…
The XLZD Design Book: Towards the Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics
XLZD Collaboration, J. Aalbers, K. Abe +441
This report describes the experimental strategy and technologies for XLZD, the next-generation xenon observatory sensitive to dark matter and neutrino physics. In the baseline desi…
Demonstration of the light collection stability of a PEN-based wavelength shifting reflector in a tonne scale liquid argon detector
V. Gupta, G. R. Araujo, M. Babicz +18
Liquid argon detectors rely on wavelength shifters for efficient detection of scintillation light. The current standard is tetraphenyl butadiene (TPB), but it is challenging to ins…
