The mission of the Topical Collaboration on Nuclear Theory for Double Beta Decay and Fundamental Symmetries (the DBD Collaboration), which involves nine universities and two national labs, is to use theoretical nuclear physics to address questions about fundamental particles and symmetries. In particular, we work to understand the implications for neutrinos and for physics beyond the standard model of experiments to observe neutrinoless double-beta decay, measure hadronic and atomic electric dipole moments, and detect particle dark matter. Doing so requires accurate calculations , with meaningful uncertainty estimates, of both hadronic and nuclear matrix elements.
We are funded in part through The Department of Energy, Office of Science, Office of Nuclear Physics.
