标题： Multiple rescattering effects in the hard knockout reaction $\mathbf{^2\mbox{H}(p,2p)n}$

摘要： 质子与氘核的相互作用是最简单的核反应。 然而，它允许研究核介质效应的前驱现象，如初始态/最终态相互作用（ISI/FSI）。 在硬质质子剥离的情况下，ISI/FSI偏离“标准”值可能携带颜色透明性的信号。 在这方面，尽可能精确地定义“标准”是很重要的。 本工作继续在广义射线近似（GEA）框架内的先前研究。 重点是参与质子在观察中子上经历多次软散射的过程。 结果表明，正确处理出射质子轨迹偏离纵向方向的偏差，会导致具有两个出射质子软散射的部分振幅显著改变，以及具有入射和出射质子散射的非零振幅。 对多次散射的新处理在具有前向观察中子的动量范围内很重要。 显示英文摘要

摘要： The interaction of a proton with a deuteron is the simplest nuclear reaction. However, it allows the study of precursors of nuclear medium effects such as initial-state/final-state interactions (ISI/FSI). In case of hard proton knockout, the deviation of ISI/FSI from the 'standard' values may carry a signal of color transparency. In this regard, it is important to define the 'standard' as precisely as possible. This work continues previous studies within the framework of the Generalized Eikonal Approximation (GEA). The focus is on processes where the participating protons experience multiple soft rescattering on the spectator neutron. It is shown that correct treatment of deviations of the trajectories of outgoing protons from the longitudinal direction leads to a significant modification of partial amplitudes with soft rescattering of two outgoing protons and non-vanishing amplitudes with rescattering of incoming and outgoing protons. The new treatment of multiple rescattering is important in kinematics with a forward spectator neutron.
