Model of elementary particles with substructures moving in positive and negative time directions

A new theory of elementary particles is developed with the assumption that all real and virtual particles are not point-like. The structure, the diameter, the real mass, the bare charge and the spin for the simplest leptons are determined. The volume of the elementary particle is composed of several three-dimensional curved volumes lying in a higher dimensional flat space, and the mass and the different charges are located in these different subspaces. The properties of the elementary particles can be explained by the zero point energy and by the curvatures of the subspaces. The fundamental difference between the gravitational and the electric field strength could be presented.
