Description
Monopole, generically produced in any Unification theories, can also catalyze baryon decays at an unsuppressed rate, known as the Callan-Rubakov effect. This naturally provides a source of baryon number violation in both the early Universe and late Universe. For the first time, we propose a scenario to produce the primordial baryon asymmetry using the Callan-Rubakov effect and point out potential experimental signals.
