Investigation of Baryon Number violation with CUORE

The conservation of baryon number in the Standard Model originates from an empirical symmetry and does not derive from first principles. Discovery of this symmetry breaking would have far-reaching consequences for our understanding of the universe, in particular the origin of the matter-antimatter asymmetry. A hypothesized process that can violate baryon number is the tri-nucleon decay, which involves three nucleons in a nucleus decaying simultaneously. In cases where the resulting daughter nucleus is unstable, the subsequent decay radiation can be searched for as evidence of the progenitor tri-nucleon decay. We discuss a search for tri-nucleon decay of ¹³⁰Te with CUORE using the delayed decay of expected daughter nuclei. We will present the search signatures, the associated backgrounds, and the analysis techniques employed.
