SUMMARY
The Standard Model (SM) allows for proton decay, albeit with extremely low probabilities compared to Grand Unified Theories (GUTs). This decay mechanism is non-perturbative and is attributed to topological effects within the framework of the SM. Although the contribution to proton decay is minimal, it remains theoretically detectable and has implications for leptogenesis models, which garnered significant interest among cosmologists in the early 1990s. Relevant literature includes T'Hooft's original 1976 paper and two experimental papers that provide foundational insights into this phenomenon.
