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…
