摘　　要：本文采用中性介子π0与核子N-反核子U-强相互作用的Lorentz不变耦合模型,对质子反质子在中性介子π0重整化链图传播下的散射微分截面,作了严格解析计算后获得了"精确"理论结果;进而,又对该计算结果与π0树图传播下的微分截面作了对比分析,获得了相关辐射修正的重要结果.这对于深入研究质子摊贩质子在高、中、低能区中的弹性碰撞及其描述强相互作用的Lorentz不变耦合模型理论,都将提供某些值得借鉴与参考的理论研究价值.In the Lorentz coupling model of strong interaction between neutral meson π^0 and N -N^-, we have strictly analytic calculated the scattering differential cross-section of p - p^- about the no renormalized chained propagator and obtained accurate theoretical outcome. Moreover, after comparing with the differential crosssection of π^0 tree propagator, we have obtained related radiation correction outcome. 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.
