%X In the work, we make a detailed discussion on the reaction, via nucleon-antinucleon propagator, within the SU (2)-invariant coupling model between charged mesons and nucleons (¦Ð¡ÀN) of perturbation theory of quantum field theory. The renormalized loop-chain propagator of nucleon-antinucleon (N-N) was strictly calculated and given an analytical expression with the large momentum integral limitation method. Furthermore, we obtain a simple and analytic expression of the differential cross-section of p* renormalized loop-chain propagator, i.e. *. We also calculate and obtain numerical results of the differential cross-section of p* at tree, one-loop and chain diagram in different center-of-mass energy, respectively, and make a detailed comparison and discussion and show some important information about radiative correction. In large energy within 2.5 GeV¡Üp0¡Ü100 GeV, these corrections are in the reasonable range, i.e. *<2.0. The results provide a significant reference to understand in-depth of the SU(2)-invariant coupling model of strong interactions theory and to explore the reaction crossª²section between mesons and nucleons (¦ÐN). In addition, it will provide effective reference to the applicability of the perturbation theory of quantum field theory in nucleon interactions, the renormalized calculation in different ways and approaches.(* Indicates a formula, please see the full text)
