We then calculate the relevant scale parameter, $\\Lambda_T$, which characterizes the running of $\\tilde{g}^2(T)$ with $T$, using the background field method in the static sector. It is found that $\\Lambda_T/\\Lambda_{\\overline{\\text{MS}}} =e^{(\\gamma_E+1/22)}/(4\\pi)\\approx 0.148$. We further verify that the coupling $\\tilde{g}^2(T)$ is also optimal for lattice perturbative calculations.
