alpha_s from tau decays revisited
D. Boito, O. Cata, M. Golterman +4
Being a determination at low energies, the analysis of hadronic tau decay data provides a rather precise determination of the strong coupling alpha_s after evolving the result to M…

Issues in determining alpha_s from hadronic tau decay and electroproduction data
D. Boito, O. Cata, M. Golterman +4
We discuss some key issues associated with duality-violating and non-perturbative OPE contributions to the theoretical representations of light quark current-current two-point func…

Duality Violation and the K --> pi pi Electroweak Penguin Operator Matrix Elements from Hadronic Tau Decays
D. Boito, O. Cata, M. Golterman +4
We discuss a preliminary study of the impact of duality violations on extractions from tau decay data of the D=6 VEVs which determine chiral limit Standard Model K-->pi pi matrix e…
