J. E. Ramírez, Bogar Díaz, C. Pajares

AI总结:

本文研究强子碰撞中色弦的径向分布函数,通过在弦中引入同心核心及核心重叠概率提供排斥相互作用,发现气液与禁闭-解禁闭相变温度差较小的系统,从而解释了夸克-胶子等离子体的液体行为。

摘要:

我们研究强子碰撞中形成的色源(弦)的径向分布函数,以及获得液体所需的条件。由于需要排斥相互作用,我们在弦中引入同心核心,并设定弦允许核心-核心重叠的概率。我们发现了气液相变与禁闭-解禁闭相变温度之差较小的系统。这解释了在禁闭-解禁闭相变温度之上实验观测到的夸克-胶子等离子体的液体行为。

英文摘要:

We study the radial distribution function of the color sources (strings) formed in hadronic collisions and the requirements to obtain a liquid. As a repulsive interaction is needed, we incorporate a concentric core in the strings as well as the probability that a string allows core-core overlaps. We find systems where the difference between the gas-liquid and confined-deconfined phase transition temperatures is small. This explains the experimentally observed liquid behavior of the quark-gluon plasma above the confined-deconfined transition temperature.
