Fitting lattice data of VPF to the continuum perturbative formula including the operator product expansion, we extract the QCD scale parameter \$Łambda\_MS^(3)\$. At the \$Z\$ boson mass scale, we obtain \$\alpha\_s^(5)(M\_Z)=0.1181(3)(^+14\_-12)\$, where the first error is statistical and the second is our estimate of various systematic uncertainties.
