The chiral properties of the fermion-monopole system are investigated in detail. For one species of massless Dirac fermions, we show that the chiral symmetry is spontaneously broken, even in the presence of anomalies. The symmetry breaking is accompanied by a Nambu-Goldstone mode in the physical sector, which essentially coincides with the bosonic fields employed by Rubakov and Callan. A discrepancy noted previously for a Higgs-boson mass is also resolved. For the case of two species, we find two classes of degenerate solutions corresponding to whether or not the non-anomalous chiral symmetry is broken. A comparison of the two solutions in the presence of a mass term indicates that monopoles are unlikely to catalyze proton decay at strong-interaction rates. © 1985 The American Physical Society.
