论文摘要
我们回顾了无弹性中膜膜散射的研究。在具有手性扰动理论的非扰动方案中，在基于有效的介子拉格朗日人的模型中，无弹性的介子 - 梅森 - 梅森散射导致成功地识别梅森 - 膜反应中的共鸣，充分鉴定出充分的粒子中最终状态相互作用的含量。对于每个由夸克和古夸克组成的介子，无弹性的介子 - 梅森散射可能是由夸克 - 易夸克（Quark-Antiquark）歼灭，夸克 - 易夸克（Quark-Antiquark）创建，夸克交叉互换和夸克 - 易药灭绝和创造引起的。在介子散射中的中夸克 - 静脉相对运动波函数的过渡幅度中，取决于辐射物质，并且在扰动的量子染色体动力学中给出了过渡势。通过过渡幅度，非弹性介子膜散射的横截面取决于辐射物质的温度。发现了横截面的一些显着温度依赖性。在大型强子对撞机上的质子 - 普罗顿碰撞和铅铅碰撞中，无弹性中膜及其散射变得更加重要。
We review studies of inelastic meson-meson scattering. In nonperturbative schemes with chiral-perturbation-theory Lagrangians and in models based on effective meson Lagrangians, inelastic meson-meson scattering leads to the successful identification of resonances in meson-meson reactions, adequate inclusion of final state interactions in particle decays, and so on. For mesons of which each consists of a quark and an antiquark, inelastic meson-meson scattering may be caused by quark-antiquark annihilation, quark-antiquark creation, quark interchange, and quark-antiquark annihilation and creation. In transition amplitudes for meson-meson scattering mesonic quark-antiquark relative-motion wave functions depend on hadronic matter, and transition potentials are given in perturbative quantum chromodynamics. Via transition amplitudes the cross sections for inelastic meson-meson scattering depend on the temperature of hadronic matter. Some prominent temperature dependence of the cross sections has been found. Inelastic meson-meson scattering becomes even more significant in proton-proton collisions and lead-lead collisions at the Large Hadron Collider.
