The Nuclear Theory of Neutrinoless Double-Beta Decay
Argonne Physics Division Colloquium - 6 Mar 2020
11:00 AM, Building 203 Auditorium

Groups around the world are gearing up to construct ton-scale experiments to observe neutrinoless double-beta decay, which, if it occurs, has profound implications for fundamental physics. To plan such experiments and extract useful information from their results, one needs values for the nuclear matrix elements that help determine the decay rate. These matrix elements cannot be measured and so we must use our knowledge of nuclear physics to compute them. The DOE is currently funding a five-year topical collaboration with the goal of providing accurate nuclear matrix elements with quantified uncertainty. I report on recent progress made by the collaboration, with emphasis on nuclear structure but also with some discussion of QCD and effective field theories.
