Abstract

Through the research contained in this proposal we want to address important nuclear physics aspects of three experimental programs of very high scientific profile; all of them aimed at searching for signals of physics beyond the Standard Model: - The search for neutrinoless beta decay. - Efforts to detect particle dark matter through its scattering off nuclei. - Measurements of the correlation between emitted particles in very low-energy beta decay. These ambitious goals are directly related to current frontiers in modern ab initio nuclear theory. We will therefore pursue two computational lines of research with mutual connections (see Resource usage for details): 1. The development of state-of-the-art many-body solvers for quantum systems of strongly-interacting particles. 2. The study of nuclear interactions and currents from chiral effective field theory. The significance and timeliness of this research project can be traced to major recent advances in theoretical physics and high-performance computing, and to the current worldwide development of low-energy subatomic physics experiments.
