论文摘要
我们使用弛豫时间近似的新表述,使用QCD启发的能量依赖性的松弛时间和现象学热质量从拟合到晶格QCD热力学获得的现象学热质量来始终如一地计算大块和剪切粘度系数。方便地选择匹配条件以简化计算。
We use a novel formulation of the relaxation time approximation to consistently calculate the bulk and shear viscosity coefficients using QCD-inspired energy-dependent relaxation times and phenomenological thermal masses obtained from fits to lattice QCD thermodynamics. The matching conditions are conveniently chosen to simplify the computations.
