Symmetry and Exact Dyon Solutions for Classical Yang-Mills Field Equations

摘要

We show that the conserved magnetic and electric charges in non-Abelian theories have nothing to do with the Higgs scalars and/or the symmetry structure of the Lagrangian. They are a consequence of the local isospin gauge symmetry. We present several exact static dyon solutions to the non-linear classical field equations in both massless and massive Yang-Mills theories, which possess both electric and magnetic charges.
