After a first glimpse of LEGEND-200 data at TAUP 2023, LEGEND-200 continued accumulating exposure and performed its first unblinding of the signal region. These results were presented at Neutrino 2024, which include the first half-life limit of 0νββ from LEGEND data! The Collaboration was represented by 1 talk and 12 posters covering a wide rage of topics including background modeling, application of machine learning methods, and the use of a novel scintillating material for background suppression.

Large Enriched Germanium Experiment for Neutrinoless ββ Decay - LEGEND

The LEGEND collaboration is comprised of over 250 researchers from about 50 institutions from around the world, working together to develop the largest ⁷⁶Ge neutrinoless double-beta decay experiment in history. By combining the technological expertise and experience from the GERDA experiment and MAJORANA DEMONSTRATOR, LEGEND is expected to reach a design sensitivity two orders of magnitude greater than its predecessors.

The physics case

Majorana neutrinos

Since their discovery, neutrinos have been an object of extensive experimental study and the knowledge about their properties has advanced our understanding of weak interactions significantly. Still unanswered, however, is the very fundamental question whether the neutrino is identical to its anti-particle...
