TL;DR
This paper investigates the use of anisotropic lattices and the link-integration method to compute transport coefficients of the quark-gluon plasma, focusing on improved actions and parameter effects in medium to strong coupling regions.
Contribution
It introduces the application of anisotropic lattices combined with the link-integration method to calculate transport properties of the quark-gluon plasma.
Findings
The $eta$ and $ heta$ parameters have small self-energy effects.
The link-integration method effectively determines the $ heta$ parameter in medium to strong coupling.
Anisotropic lattices facilitate the calculation of quark-gluon plasma transport coefficients.
Abstract
We have studied the link-integration method for the improved actions. With this method the parameter in the medium to strong coupling regions is obtained. Effects of the self-energy terms for the parameters are small in the regions of and studied. After these investigations, the anisotropic lattice is used for the calculation of transport coefficients of the quark gluon plasma.
