Description
High Purity Germanium (HPGe) detectors offer exceptional spectroscopic performance, detailed event-topology reconstruction, and outstanding radiopurity, making them uniquely suited to search for the neutrinoless double beta (0nbb) decay of Ge76. The Large Enriched Germanium Experiment for Neutrinoless ββ Decay (LEGEND) is a staged experimental program dedicated to the discovery of this rare process using enriched HPGe detectors in a low-background liquid argon environment.
The first phase, LEGEND-200, is currently collecting data at the Laboratori Nazionali del Gran Sasso. The analysis procedure comprises the data transformation from raw digitized waveforms to the high-level event observables, incorporating digital signal processing, automated energy calibration, and background rejection through pulse shape analysis and liquid argon coincidences. This poster describes the analysis workflow as implemented within the Julia-based analysis framework, JuLeAna.
