The Renormalization Calculation And Research Of Strong-coupling Apex Angle

Since the beginning of last century, quantum field theory, based on quantum mechanics and special relativity, comes through much development and improvement. And now it becomes one of the most important basic theories for quantum electric mechanics, quantum gage 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 annihilation particle and even exploratory new particles and new physics phenomenon. However, the research of calculation method holds the extremely important position when describing theory using quantum field theory for a long time. So kinds of theoretical calculation methods exist. At present, the research on the calculation method of quantum field theory becomes one of the most important contents in this field, which is highly concerned by theoretical physical scientist.In this dissertation, we have calculated the apex angle renormalization quantity of strong coupling unicycle graph and obtained very useful results, 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 and its background. Secondly, 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, so we separated finite quantity from infinite quantity and obtained the analytical form. Thirdly, we divided the analytical form into two parts after doing analysis and simplification. One is primary function and the other is transcendental function. At the same time, we dealt with the drift small quantityεof pole reasonably, which would do a great favor for later calculation. Forth, we calculated the two parts separately and obtained very useful results. At last, we obtained the radiation correction results after analyzing deeply.In this dissertation, we have done some valuable research on the renormalization calculation of quantum field theory. This dissertation has high academic value in theoretical physics research. This dissertation is difficult to some extent. And its results can be used for the future calculation of renormalization quantity. So it can be as a reference for this field.
