In high energy heavy ion collisions a hot and dense medium is formed. In these media large back-to-back correlations of protons and anti-protons are observable in ultra-relativistic collisions, similarly to the Andreev reflection of electrons off the boundary of a super conductor. While quantum statistics normally should suppress such behavior the in-medium correlations should promote them so that they could theoretically become of similar strength as bosonic back-to-back correlations. So far only perfect in-medium configurations have been considered possibly limiting the analysis performed so far requiring to look at the interacting case.

在RHIC哪里寻找强子压缩的相关性

在高能重离子碰撞中，会形成热的致密介质。在这些介质中，超相对论碰撞中可观察到质子和反质子的大背靠背关系，类似于电子在超导体边界上的安德列夫反射。虽然量子统计通常应抑制这种行为，但中等相关性应促进它们的作用，以便它们在理论上可以具有与玻色背对背相关性相似的强度。到目前为止，仅考虑了完美的中型配置，可能限制了迄今为止需要进行交互分析的分析。
