Abstract

We review the determination of $α_{s}$ that follows from comparing at short distances the QCD static energy at three loops and resummation of the next-to-next-to leading logarithms with its determination in 2+1-flavor lattice QCD provided by the HotQCD collaboration. The result that we obtain is $α_{s}$ (1.5 GeV) = 0.336 $_{- 0.008}^{+ 0.012}$ , corresponding to $α_{s}$ (M_Z) = 0.1166 $_{- 0.0008}^{+ 0.0012}$ . We outline future possible developments.
