摘要
The symmetry of the in-group particles, which are of three-generation fermions, and the “out-group” ones, which are not admitted by three-generation fermions, is discussed. It was found that the “out-group” antiparticles of Bose type, which came into being because of CP （ charge Conjugation-Parity conservation） violation in the early universe and became heavier due to the phase transformation from low temperature to high temperature, are the supersymmetric companions of the in-group particles of Fermi type. The ratio of the number density of photons to that of protons calculated with Planck distribution method is about 0.61× 10^10, which is close to the observed value （ about 10^10） available in literature. A theoretical analysis of the structure of a photon suggests that the photon has a quark-gluon structure, which is consistent with the experimental result reported in literature. As the lightest particle in the supersymmetric companions, the calculated mass of a neutralino is 320 GeV. The so-called “vast area of desert” in mass scale appears to be the supersymmetry area of the three-generation particles, and “neutralinos” are the source of the moving of galaxies and the dark matter of non-baryons.
