A simplified model for monopole catalysis of nucleon decay

We present a simple model where a nucleon is treated as a skyrmion, both th e monopole and skyrmion are smooth solutions of the classical field equatio ns, the baryon number nonconservation is explicitly built in and is due to the classical analogue of the triangle anomaly v, and there is no necessity to consider leptons. We show by numerical analysis that there are no stati c classical solutions with a nonzoro baryon number oil top of the monopole, i.e., that the monopole catalysis of skyrmion decay indeed proceeds classi cally.
