Heavy solitons in generalized spinor electrodynamics

The generalization of spinor electrodynamics proposed by V. G. Kaldyshevskii, in which distortion of momentum space is taken into account, is considered. In the heavy-particle approximation, the structure of a possible soliton solution of the equations of motion which is invariant relative to a sequence of permissible groups of transformations is established. Numerical estimates of the mass and magnetic moment of the charged state with spin 1/2 are made. © 1990 Plenum Publishing Corporation.
