Neutrinoless Double Beta Decay: Beyond the "Tonne-Scale" - I

Neutrino-less double beta decay is the most sensitive probe of lepton number violation and a powerful tool to study the origin of neutrino masses. Currently, experimental efforts are gearing up for the so-called "tonne-phase" searches, with sensitivity reach of T_1/2 ~ 10^28 years. In the US, this phase is under the stewardship of the DoE Office of Nuclear Physics.

This workshop aims at defining experimental paths for studying neutrinoless double beta decay beyond the "tonne-scale" and at providing theoretical guidance. From the theoretical point of view, it is important to frame both discoveries or lack thereof made by the tonne-scale experiments. The experimental challenges include reaching ~100x higher sensitivity (T_1/2 ~ 10^30 years) and extracting more information from double-beta decay events. The workshop is organized in the broader context of the Snowmass 2021 process. It follows the collection of numerous DBD-flavored LOIs in Summer 2020, and is meant to define the main thrusts along which contributed papers will be prepared in 2021 and to identify both goals and the community to carry this program in the coming 1-2 decades. The hope is to have an in-person 'part II' event in May 2021 to
