标题： Transport coefficients in high temperature gauge theories: (II) Beyond leading log

摘要： 高温度QCD和QED中剪切粘度、味扩散常数和电导率的完整一阶评估结果被呈现出来。 与规范相互作用相关的库仑对数表明，输运系数的一阶结果本身可能在1/log(1/g)的幂级数中展开；也考察了这种展开的实用性。 发现次对数近似在德拜质量小于温度的情况下可以很好地近似完整的领先阶结果。 显示英文摘要

摘要： Results are presented of a full leading-order evaluation of the shear viscosity, flavor diffusion constants, and electrical conductivity in high temperature QCD and QED. The presence of Coulomb logarithms associated with gauge interactions imply that the leading-order results for transport coefficients may themselves be expanded in an infinite series in powers of 1/log(1/g); the utility of this expansion is also examined. A next-to-leading-log approximation is found to approximate the full leading-order result quite well as long as the Debye mass is less than the temperature.
