标题： Heavy Quark Momentum Broadening in a Non-Abelian Plasma away from Thermal Equilibrium

摘要： 我们进行了经典统计实时格点模拟，以计算强耦合非阿贝尔规范场存在时夸克的实时谱函数和动量展宽。基于一种提取相对论夸克动量展宽的新方法，我们发现由于夸克从介质中接收的关联动量冲击，其动量分布表现出有趣的整体性特征，并最终进入扩散区域。我们提取了描述粲夸克和底夸克质量范围内的动量扩散系数，并发现与重夸克极限相比存在显著差异。 显示英文摘要

摘要： We perform classical-statistical real-time lattice simulations to compute real-time spectral functions and momentum broadening of quarks in the presence of strongly populated non-Abelian gauge fields. Based on a novel methodology to extract the momentum broadening for relativistic quarks, we find that the momentum distribution of quarks exhibit interesting non-perturbative features as a function of time due to correlated momentum kicks it receives from the medium, eventually going over to a diffusive regime. We extract the momentum diffusion coefficient for a mass range describing charm and bottom quarks and find sizeable discrepancies from the heavy quark limit.
