Phenomenal Theory Of "Unitification" Aboat Four Nucleon Resonance State Strong Decay

Since the beginning the last century, quantum field theory, based on quantum mechanics and special relativety, comes through much improvement. And now it becomes one of the most important basic theories for quantum electric mechanics, quantum theory, quantum chromo-dynamics, 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 annihilationParticle and even exploratory new particles and new physics phenomenon. It constitute kinds of theoretical calculation methods when describing theory using quantum field theory for a long time.In this dissertation, When we research the four nucleon resonance, we have calculated a special phenomenal theory of unitification about four nucleon resonance state strong decay, using the strong interaction between nucleon(ant-nucleon) and neutral meson of quantum field theory under the Lorentz constant coupling model. Firstly, we introduced completely the form of renormalization theory, Its background, And pertubative theory of quantum theory. Secondly, In the traditional phenomenal theory of"Unitification", we analyzed and calculated the decay width about four nucleon resonance state strong decay to nucleon andπ0 meson .Thirdly, when we introduced the Weinberg′s idea of additional differentiative coupling ,we have calculated the decay width between nucleon(ant-nucleon) and neutral meson of quantum field theory under the Lorentz constant coupling model, using a special phenomenal theory of unitification. Finally, In order to obtain precise solution, we analyzed and calculated the apex angle renormalization quantity of strong coupling unicycle graph between nucleon(ant-nucleon) and neutral meson with the method of momentum normalization, we obtained the radiation correction results after analyzing deeply.In this dissertation we have done some valuable research on the special phenomenal theory of unitification to the strong interaction between nucleon(ant-nucleon) and neutral meson of quantum field theory under the Lorentz constant coupling model. and this dissertation has high academic value in theoretical physics research.
