论文摘要
可以从langevin的描述方面理解,可以理解Quark-Gluon等离子体中低动量夸克的能量损失模式。在热平衡中,可以用单个重夸克动量扩散系数kappa进行参数化,该系数需要非扰动地确定。在这项工作中,我们研究了gluonic等离子体中Kappa对静态夸克的温度依赖性,并特别强调了重离子碰撞实验的感兴趣温度范围。
The energy loss pattern of a low momentum heavy quark in a deconfined quark-gluon plasma can be understood in terms of a Langevin description. In thermal equilibrium, the motion can then be parametrized in terms of a single heavy quark momentum diffusion coefficient kappa, which needs to be determined nonperturbatively. In this work, we study the temperature dependence of kappa for a static quark in a gluonic plasma, with a particular emphasis on the temperature range of interest for heavy ion collision experiments.
