DESCRIPTION:Speakers: Luigi Pertoldi (TUM & INFN)\n\nThe LEGEND project is
  a multi-phase experimental program designed to search for neutrinoless do
 uble beta (0νββ) decay in Ge-76 with the ultimate goal of probing beyon
 d the inverted ordering of neutrino masses. This process\, if observed\, w
 ould create matter without antimatter\, violating lepton number conservati
 on and demonstrating that neutrinos are Majorana particles. LEGEND-200 is 
 the first phase of this effort\, operating at the Gran Sasso National Labo
 ratory. It employs high-purity germanium detectors immersed in an ultra-lo
 w background liquid argon environment\, which is instrumented with optical
  sensors to detect its scintillation light. This setup acts as both a pass
 ive and active veto against residual backgrounds\, significantly enhancing
  the experiment’s sensitivity. In this seminar\, I will present the firs
 t results from LEGEND-200\, including detector performance\, background su
 ppression strategies\, and the current limit on the half-life of 0νββ 
 decay in Ge-76. I will also summarize the status of the planning for LEGEN
 D-1000\, the final phase of the experiment\, which is designed for an unam
 biguous discovery of 0νββ decay beyond the inverted ordering by operat
 ing 1 ton of germanium detectors.\n\nhttps://agenda.infn.it/event/46142/
