Teacher: Now, understand the problem? Solve this instance: These entities can enhance the s-wave component of fermion wave functions through the Callan-Rubakov effect. Hooft suggested that a topological excitation present in the non-abelian Higgs model was one of these entities. The lower bound for their mass is obtained from the Bogomol'nyi bound, and in the (*) Witten effect, fermion interactions convert them to dyons. Their existence would explain the quantization of electric charge according to Dirac. For 10 points, name these hypothetical particles that posses a magnetic charge.
