论文摘要

在$ \ sqrt {s_ {nn}} = 2.76 $ TEV的中央PB-PB碰撞中中性和带电的KAON之间的动态相关性测量,Alice Collaboration显示出相对于常规重型ION碰撞模拟器,例如AMPT,EPOS,EPOS和HIJing。我们考虑了其他常规统计模型,没有一个可以再现相关性的幅度和中心性依赖性。数据可以通过从中心性增加的域和体积增长的域的相干发射来复制。我们表明,奇怪夸克释放的能量可能足以解释异常。

Measurements of the dynamical correlations between neutral and charged kaons in central Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV by the ALICE Collaboration display anomalous behavior relative to conventional heavy-ion collision simulators such as AMPT, EPOS, and HIJING. We consider other conventional statistical models, none of which can reproduce the magnitude and centrality dependence of the correlations. The data can be reproduced by coherent emission from domains which grow in number and volume with increasing centrality. We show that the energy released by condensation of strange quarks may be sufficient to explain the anomaly.
