论文摘要

我们采用QCD动力学理论,包括偶联常数的临近领先(NLO)级校正,以研究弱耦合的非亚洲等离子体向热平衡的演变。对于两个具有不足或过度初始条件的特征远面平衡系统,NLO校正在各种耦合方面仍处于良好的控制状态,而NLO校正的总体效果是降低了热化所需的时间。

We employ the QCD kinetic theory, including next-to-leading(NLO) order corrections in coupling constant, to study the evolution of weakly coupled non-Abelian plasmas towards thermal equilibrium. For two characteristic far-from-equilibrium systems with either under- or over-occupied initial conditions, the NLO corrections remain well under control for a wide range of couplings, and the overall effect of NLO corrections is a reduction in the time required for thermalization.
