Proton decay experiments strongly constrain models in which baryon number is violated. Typical models must be associated to very high-energy scales to be viable, making them hard to probe with independent methods. An interesting class of models, which has gained significant attention in recent years, still violate baryon number but only by two units such that the proton remains stable. The last years have seen interesting developments in the associated particle, hadronic, and nuclear theory and the connection to outstanding cosmological problems such as the matter-antimatter asymmetry. In addition, future measurements made by the ESS NNBar Collaboration, DUNE, PNPI Gatchina, and Hyper-Kamiokande in the realm of dinucleon decay and neutron-antineutron transformations have real discovery potential.
In this focused workshop, we wish to bring together practitioners of the various communities, both theoretical and experimental, to discuss what are the challenges and prospects for the detection of baryon number violation in the near future, and what would be the implication of signals or lack thereof.
