The collaboration aims to develop a phased, 76Ge based double-beta decay experimental program with discovery potential at a half-life beyond 1028 years, using existing resources as appropriate to expedite physics results.
We are proposing a next-generation, ton-scale neutrinoless double-beta (0νββ) decay experiment that builds on the successes of the current generation experiments searching for the 0νββ decay of 76Ge. An observation of 0νββ would have a profound impact on extending the standard model of physics and our understanding of the imbalance of matter and anti-matter in the Universe.

The LEGEND collaboration has defined an experimental program with the goal to discover new physics and explore the role of neutrinos in the matter/antimatter asymmetry in the universe. The LEGEND project is proposed in response to the U.S. Nuclear Science Advisory Committee’s 2015 Long Range Plan recommendation for “…the timely development and deployment of a U.S.-led ton-scale neutrinoless double-beta decay experiment.”
The LEGEND baseline technical design is centered around the demonstrated low-background and excellent energy performance of p-type, point-contact high-purity Ge semiconductor detectors, enriched to over 88% in 76Ge. The current MAJORANA DEMONSTRATOR and GERDA experiments have set the best detector resolution and lowest background of any neutrinoless double-beta decay search using Ge-based technology. The LEGEND collaboration is proposing the deployment of 1000 kg of 76Ge in a deep underground laboratory as the LEGEND-1000 experiment.
