摘要

分析了Ising模型中的非弹性效应。将伊辛模型视为具有能量密度算子\(\varepsilon \)扰动磁场的伊辛场论。这个算符的包含导致理论中最轻粒子的散射，形成两个粒子（质量最轻的和次轻的）。计算了高能量和阈值以上的散射截面，确定了其渐近形式。

Inelastic Effects in the Ising Model

Inelastic effects in the Ising model are analyzed. The Ising model is considered as the Ising field theory with a magnetic field perturbed by the energy density operator \(\varepsilon \). The inclusion of this operator leads to the emergence of the scattering of the lightest particles in the theory with the formation of two particles (the lightest and the next in mass). The scattering cross section is calculated and its asymptotic forms are determined for high energies and above the threshold.
