From electron-positron and tau decays, sum-rule analyses yield alpha_s(MZ)=0.1176 (fixed-order) or 0.1201 (contour-improved), confirm a roughly six-fold violation of four-quark condensate factorization, and see no evidence for duality violation.

QCD condensates and $\alpha_s$ from $e^+e^-$ and $\tau$-decays
From electron-positron and tau decays, sum-rule analyses yield alpha_s(MZ)=0.1176 (fixed-order) or 0.1201 (contour-improved), confirm a roughly six-fold violation of four-quark condensate factorization, and see no evidence for duality violation.
