Anticommutative electric and magnetic charges, and the monopole question

The monopole question is treated anew in the light of a recent, strictly covariant, extended formulation of fermion quantum field theory naturally including also a pseudoscalar variety of conserved charges. The essential novelty lies in the resulting quantum property of anticommutivity between scalar and pseudoscalar charge varieties, which should in particular apply to electric and magnetic charges. As an immediate outcome, there should no longer be any (Dirac-like) quantization condition relating these charges and binding the magnetic elementary charge to have a very great strength. A generalized Lagrangian approach to the monopole problem is made truly viable, leading to two independent local gauge couplings which are separately generated by the electric and magnetic elementary charges and are not allowed to interfere. This would prevent electric and magnetic monopoles from mutually interacting and would particularly account for the "absence" of magnetic sources in ordinary electromagnetism. Within such a framework, an electric charge eigenstate with a nonzero eigenvalue is bound to have a null magnetic charge expectation value, and the magnetic dipole moment of an electrically charged point fermion may actually be seen as resulting from the additional internal presence of a single magnetic charge subjected to a maximal uncertainty in sign. An easy estimate makes it allowable to assign to this charge a strength just equal to that of the partner electric charge. Such a conjecture leads to a "dual" model of a charged point fermion where the "electric" and "magnetic" roles can well be interchanged with no observable effects. In the associated formalism, duality symmetry is already included without the need to appeal to any "missing" electromagnetic phenomenology to be discovered.
