手征磁效应与手征相变

Chiral Magnetic Effect and Chiral Phase Transition

Wei-jie Fu, Yu-xin Liu, Yue-liang Wu

摘要:

研究了手征相变对手征磁效应的影响。计算了方位角电荷粒子关联随温度的变化。结果发现,当温度达到QCD相变的临界值时,关联中存在一个明显的尖点。据预测,当RHIC中的碰撞能降低到临界值以下时,电荷-粒子关联将受到剧烈的抑制。我们发现,在RHIC能量扫描实验中,方位角电荷-粒子关联可以作为识别QCD相变发生的信号。

英文摘要:

We study the influence of the chiral phase transition on the chiral magnetic effect. The azimuthal charge-particle correlations as functions of the temperature are calculated. It is found that there is a pronounced cusp in the correlations as the temperature reaches its critical value for the QCD phase transition. It is predicted that there will be a drastic suppression of the charge-particle correlations as the collision energy in RHIC decreases to below a critical value. We show then the azimuthal charge-particle correlations can be the signal to identify the occurrence of the QCD phase transitions in RHIC energy scan experiments.
