Abstract

Measurements of momentum space correlations in heavy ion reactions represent unique tools to investigate the properties of the created medium. However, these analyses require the careful handling of the final state interactions such as the Coulomb repulsion of the involved particles. In small systems such as \({{e}^{ + }} + {{e}^{ - }}\) or p + p the well-known Gamow factor gives an acceptable description but in the case of extended sources like those created in heavy ion collisions, a more sophisticated approach has to be developed. In this paper we expand our previous work on the investigation of the Coulomb final state interaction in the presence of a Lévy source. Such sources were shown to be a statistically acceptable assumption to describe the quantum statistical correlation functions in high energy heavy ion reactions.

存在列维源的库仑最终状态相互作用的扩展经验公式

摘要

重离子反应中动量空间相关性的测量代表了调查所创建介质性质的独特工具。但是，这些分析需要仔细处理最终状态的相互作用，例如所涉及粒子的库仑排斥。在小型系统中，例如\（{{e} ^ {+}} + {{e} ^ {-}} \）或p + p众所周知的Gamow因子给出了可以接受的描述，但是在扩展源（如在重离子碰撞中产生的扩展源）的情况下，必须开发一种更复杂的方法。在本文中，我们扩展了先前在存在Lévy源的情况下对库仑最终状态相互作用进行研究的工作。这些来源被证明是描述高能重离子反应中量子统计相关函数的统计学上可接受的假设。
