Neutral Vector Mesons Electromagnetic Decay Unitification Theory Based On Weinberg Additional Derivative Coupling Model

Since the beginning of the last century, quantum filed theory, based on quantum mechanics and special relativity, comes through much improvement. And now it becomes one of the most important basic theories for quantum electric mechanics, quantum theory, quantum chromo-dynamics, and quantum electric-weak uniform theory and so on. These theories play an important role on describing the motion and interaction of microscopic high-energy particle, creation and annihilation. It constitutes kinds of theoretical calculation methods when describing theory using quantum field theory for a long time.In this thesis, we initially introduced the tradition of the electromagnetic interaction and effective lagrange density, and use this as a model, we calculated theρ~0→π~0γ,ω→π~0γ,φ→π~0γ,and J/ψ→π~0γelectromagnetic radiation decay with . The results of the theoretical and the experimental observation value analysis, found the deficiency of traditional phenomenological model. Then we adopt Weinberg additional derivative coupling ideas; make traditional theory to the unity of theory. And the four coupling parameter were determined by the unity of the phenomenological models ;Finally, based on new theoretical framework of the uniform model ,the Jψparticles may appear all other electromagnetic decay also have been made a relatively complete qualitative analysis and discussion,furher test the unified model. And from this model predicted the other can occur on electromagnetic decay phenomenon.
