The theory of electromagnetic interactions is discussed in a gauge-invariant formulation that contains not only h and c but a further universal scale, namely, a fundamental length l. The new equations of motion of the fields, which generalize the Dirac--Maxwell equations, predict that charged Dirac particles should have intrinsic electric dipole moments; this results in violation of the P and CP symmetries, and also intrinsic anomalous magnetic moments. In this approach, there arises naturally a new internal symmetry group (SU/sub tau/(2)), which can be used to describe e..mu.. universality of the electromagnetic interactions. The total Lagrangian of the theory contains a four-fermion interaction, which violates the SU/sub tau/(2) symmetry and renders possible the decays ..mu -->..3e, ..mu -->..e..gamma.., etc. An upper bound for the fundamental length l is obtained by comparing the theoretical predictions and experimental data.
