Tri-nucleon decay in 130Te with CUORE

The conservation of baryon number in the Standard Model is based on an empirical symmetry rather than being derived from fundamental principles. If evidence were to be found indicating the violation of this symmetry, it would have profound implications for our understanding of the universe, particularly regarding the origin of the matter-antimatter imbalance. One proposed mechanism that could break the conservation of baryon number is tri-nucleon decay, which involves the simultaneous decay of three nucleons within a nucleus. The resulting decay products are emitted with energy in the GeV range, making them a promising signal for detection in the CUORE experiment. In cases where the daughter nucleus following the decay is unstable, the subsequent decay radiation can provide an additional signature in coincidence with the emitted energy. In our presentation, we will provide a comprehensive overview of the search signatures, the background factors involved, and the analysis techniques utilized in this investigation.
