采用中性介子π0与核子N-反核子(N)强相互作用的Lorentz不变耦合模型,对质子P-反质子(p)重整化链图传播下p(p)→2π0反应微分截面作了严格解析计算,获得精确理论结果;并通过将该计算结果与质子P-反质子(P)树图和重整化单圈图传播下p(p)→2π0反应微分截面作对比分析,讨论了相关辐射修正.此研究结果对于Lorentz不变耦合模型理论的深入研究与核物理的深入探索,都将提供理论计算研究方面一定的学术参考价值.the differential cross-section of p

In the Lorentz invariantcoupling model of strong interaction between neutral meson π0 and nucleon-antinucleon, we strictly calculate theproton-antiproton renormalized chain-loop propagator and obtain the accurate result of thedifferential cross-section of p(p)→2π0 with the proton-antiproton renormalized chain-loop propagator.The relevant radiative corrections are briefly reviewed and discussed. This work isinstructive for further research of the Lorentz invariant coupling model and nuclearphysics.
