    Strong coupling constant from the static energy
    Abstract: The static energy between the static quark and the static antiquark is a well studied observable on the lattice. 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 the perturbative expression and lattice data allows for precise measurement of the strong coupling constant of QCD. I will show static energy measurements from lattice simulations with a different number of dynamical fermion flavors and present the current status of extracting the strong coupling constant from this data.
