论文摘要
我们使用振幅的分析表示将弹性$ pp $散射的数据描述为具有复杂阶段的三个指数的总和。此外,我们考虑了整个转移区域中的库仑和库仑核贡献,以及大型转移区域中强大的“扰动”贡献。获得了基本散射特征的精制值。从ISR到LHC能量的过渡时,检测到振幅行为的显着变化。获得的结果表明碰撞质子的两层结构。在向13 TEV的过渡中,观察到内层的大小急剧增加及其在散射中的活性。讨论了对此效果的可能解释。
We describe data on elastic $pp$ scattering at ISR and LHC energies using the analytical representation of the amplitude as the sum of three exponentials equipped with complex phases. In addition, we take into account the Coulomb and Coulomb-nuclear contributions in the entire transfer region and strong "perturbative" contributions in the large transfer region. Refined values of basic scattering characteristics are obtained. Significant changes in the behavior of the amplitude are detected at the transition from ISR to LHC energies. The results obtained indicate a two-layer structure of the colliding protons. In the transition to 13 TeV, a sharp increase in the size of the inner layer and its activity in the scattering is observed. A possible interpretation of this effect is discussed.
