Magnetic charge as a ``hidden'' gauge symmetry (Q1891460)

Generalized electrodynamics with both electric and magnetic charges is formulated as a gauge theory with two four-vector potentials, i.e. two massless gauge fields, the ordinary Maxwell field (``electric'' photon) and a ``magnetic'' photon field. Since no magnetic massless photons have ever been observed, the author suggests to make such photons massive via a Higgs mechanism which ``hides'' the magnetic charge at energies far below the symmetry breaking energy scale.
