It is known that electromagnetic (EM) fields action on particles is limited to the Lorentz force action. In terms of spinors and currents, the EM field:
(i) rotates the Dirac current around the direction of the field $B$ to the angle proportional to the magnitude of $B$, and
(ii) "accelerates" the Dirac current in the direction of $E$ to the extent proportional to the magnitude of $E$.
Action of Lorentz force exhausts all possible rotations and boosts.
In fact, nothing else could "happen" to the Dirac current (which is a Minkowski space 4-vector) except (a) rotation and boost described above, and (b) change in magnitude of the Dirac current vector prohibited by conservation of charge and/or mass.
Unless the action of weak and strong forces is always limited to change of mass/charge of the particle, is it possible to consider the effect of these forces on particles as a kind of "special" electromagnetic action?
