The Accurate Calculation About P(?)�'p(?) Differential Cross-section Of The Renormalized π～0 Chain Propagator

Since Yukawa predicted the exixtence of pion theoretically in 1935,and it was tested by experiments in 1947,the pion has played a more and more important role in nuclear physics. With the Pion Exchange Model`s putting forward, the research of strong interaction reached its prime. In the model the pion was the media to transport the interaction between nucleons. With the model physicists have solved a great deal of problems about strong interaction, but retretfully the model has mot become the fundamental theory in the research of the strong interaction. Following that, many models were put forth to interpret the interaction between baryons and the strong interaction. Generally speaking, those models can be divided into two types—experimental theory and elementally theoretical theory. In the theoretical research, there are the Pion Exchange Model and Quark Model; while in the experimental research, there are various potential models. However, each theory has some deficiencies more or less, up to now there has not appeared a model or theory with which physicists are satisfied.In the Lorentz coupling model of strong interaction between neutral mesonπ~0 and N—N , we have strictly analytic calculated the scattering differential cross-section of p -(p|-) about theπ~0 renormalized chained propagator and obtained accurate theoretical outcome. Moreover, after comparing with the differential cross-section ofπ~0 tree propagator, we have obtained related radiation correction outcome. By comparing the two cross sections the author comes to a natural conclusion that they can deal with the interaction between nucleon and antinucleon through the Perturbation Theory.All these, we have done, can be reference for further researching p -(p|-) elastic collision at high, middle or low ergo region and description Lorentz invariant coupling model theory with strong interaction.
