Abstract

We review the determination of αs 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 αs(1.5 GeV) = 0.336-0.008+0.012, corresponding to αs(M_Z) = 0.1166-0.0008+0.0012. We outline future possible developments.
