Description
Using the most recent release of the ALEPH τ decay data, we report several relevant tests of perturbative and non-perturbative aspects of QCD. We present the most recent determination of the strong coupling constant, from an exhaustive phenomenological analysis that exploited the sensitivity to the QCD coupling in many different ways. Through the study of the left-right two-point correlation function, several order parameters of the QCD chiral symmetry breaking are determined. Implications for the Standard Model prediction of the kaon direct-CP-violating parameter ε′/ε will also be briefly discussed.
