暖化介质中的硬胶子演化

Hard gluon evolution in warming medium

F. G. Ben, M. V. T. Machado

摘要:

本文用概率微扰方法描述了硬胶子在温度随时间线性增加的稠密夸克-胶子等离子体中的能量分布。结果被应用到重离子碰撞的热化问题,在自下而上的图片的第三阶段,估计的初始时间为自下而上的第三阶段的情况。然后,当系统接近(局部)热平衡时,我们观察软热浴的熵密度和平均温度。

英文摘要:

We describe the energy distribution of hard gluons travelling through a dense quark-gluon plasma whose temperature increases linearly with time, within a probabilistic perturbative approach. The results were applied to the thermalization problem in heavy ion collisions, in the third stage of the bottom-up picture, to estimate the initial time for the third stage of the bottom-up scenario. We then look at the entropy density and average temperature of the soft thermal bath, as the system approaches (local) thermal equilibrium.
