Baryon number is an accidental symmetry of the Standard Model, and its violation would be a clear sign of new physics, with nucleon decay providing its most striking experimental signature. In this seminar, I will discuss how flavor symmetries can guide the study of baryon-number-violating (BNV) effects in the SMEFT. After briefly reviewing the main nucleon-decay signatures and the relevant dimension-six operators, I will present their classification under different flavor-symmetry assumptions and the resulting phenomenology. In particular, I will show that in some flavor scenarios the interplay with tiny neutrino masses allows proton-decay bounds to be compatible with BNV scales in the multi-TeV range. I will also comment on simple UV completions.
