    Description
The strong coupling constant $\alpha_s$ can be obtained from the static energy. For short distances, the static energy can be calculated both on the lattice, with the use of Wilson line correlators, and with the perturbation theory up to three loop accuracy with leading ultrasoft log resummation. Comparing lattice data with the perturbative expression allows for a precise measurement of the $\alpha_s$. In this talk, we will update the TUMQCD 2+1-flavor $\alpha_s$-extraction and report on the progress with the 2+1+1 extraction.
