Simple but efficient tests of QCD from $\tau$ decays
We review the determinations of the QCD coupling $\alpha_s$ from the inclusive and exclusive modes of $\tau$-decays. The most recent $\tau$-data provide the average value $ \alpha_ s \left(M^2_\tau \right)\simeq 0.347\pm 0.030 $ corresponding to $ \alpha_ s \left(M^2_Z \right) \simeq 0.121\pm 0.003...
