论文摘要

在规格理论中,带电的颗粒遵守了中等相互作用(正向散射)引起的经过修改的分散体,以高能量$ e \ geq t $导致渐近质量质量方$ M^2_ \ infty $。我们通过晶格处理其低能量有效描述静电QCD(EQCD),对强相互作用的理论计算了该质量的红外部分。将这些结果纳入有效热质量的非扰动确定将需要该数量与完整QCD的近级临近级扰动匹配。

In gauge theories, charged particles obey modified dispersion due to medium interactions (forward scattering), leading at high energies $E \geq T$ to an asymptotic mass-squared $m^2_\infty$. We calculate the infrared part of this mass nonperturbatively for the theory of the strong interactions, QCD, through a lattice treatment of its low-energy effective description, Electrostatic QCD (EQCD). Incorporation of these results into a nonperturbative determination of the effective thermal mass will require a still-incomplete next-to-leading order perturbative matching of this quantity to full QCD.
