如果强子质量在高能重离子碰撞形成的热致密介质中被修正，则粒子-反粒子对的压缩相关将会存在。虽然它们在理论上已经建立，但还没有在实验中被观察到。我们在这里提出一种明确的方法，通过分析压缩相关函数的可测量量来搜索这样的信号。我们用相对论重离子对撞机（RHIC）能量下的模拟{phi}{phi}对来说明这一建议。
Squeezed correlations of particle-antiparticle pairs were predicted to exist if the hadron masses were modified in the hot and dense medium formed in high-energy heavy-ion collisions. Although well-established theoretically, they have not yet been observed experimentally. We suggest here a clear method to search for such a signal by analyzing the squeezed correlation functions in terms of measurable quantities. We illustrate this suggestion for simulated {phi}{phi} pairs at the Relativistic Heavy Ion Collider (RHIC) energies.
