论文摘要
Pion-Nucleon弹性散射的散射幅度是通过使用非扰动项的扰动扩张的最小近似值来计算的。确定了核子的自能量，以便给出$ s $波的散射参数。结果表明，由$σ$ -Meson介导的散射过程与伪造者乳头相互作用一起起决定性作用。
The scattering amplitude of the pion-nucleon elastic scattering is calculated by the lowest-order approximation of the perturbative expansion with the non-perturbative term. The self-energy of nucleon is determined so as to give the scattering parameters of the $S$-wave. It is shown that the scattering process mediated by the $σ$-meson plays a decisive role together with the pseudovector pion interaction.
