Charge of a particle generated by a captured pair of photons
  The model of charge generation is based on the wave model of a particle, for which a brief description is given. The particle is comprised of two photons, captured in the volume of the particle, and reveals the complete relativistic behaviour. The electromagnetic waves of the two photons are supposed to induce an electrostatic field. The surface integral of this electrostatic field is identified with the charge of the particle. The magnitude of the electric field is derived from the energy density of the photons. The volume and the surface are related to the wavelength of the photons, thus leading to a charge of the particle, which is independent of its mass.
