Institute for Nuclear and Particle Astrophysics (INPA) at LBNL
The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room, located in Bldg. 50A- 5132.
The committee members are:
The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.
Please send all suggestions for future INPA talks and speakers to the INPA Committee.

Title: First results of LEGEND-200 physics data in the quest for 0νββ decay
Abstract: The Large Enriched Germanium Experiment for Neutrinoless ββ Decay (LEGEND) experimental program is dedicated to the search for the neutrinoless double-beta (0νββ) decay of Ge-76 with isotopically enriched high-purity germanium (HPGe) detectors and a discovery sensitivity beyond a half-life of 10^28 years. The project’s first phase, LEGEND-200, has stably accumulated physics data at the Laboratori Nazionali del Gran Sasso (LNGS) for over a year with 140 kg of HPGe detectors and plans to install more in the coming months. The collaboration has scrutinized this first data to assess the experiment’s sensitivity and study the composition of the LEGEND-200 residual background. This talk will present the experiment’s performance regarding background rejection and signal acceptance, a first model of the background composition before analysis cuts, and the data in the region of interest, including an updated 0νββ constraint based on the latest LEGEND data and past experiments. In addition, it will highlight the analysis procedure based on the JuLeAna software framework and focus on incorporated algorithms and techniques. The talk will conclude with an update on the experiment’s future phase, LEGEND-1000.
