(2019): Precision measurements of the QCD coupling
David d'Enterria, Stefan Kluth, S. Alekhin +50
This document collects a written summary of all contributions presented at the workshop "(2019): Precision measurements of the strong coupling" held at ECT* (Trento) in Feb. 1…
Low-energy constants and condensates from the V-A spectrum
D. Boito, M. Golterman, M. Jamin +2
We present an analysis of the isospin-one V-A correlator based on our successful simultaneous description of the OPAL V and A non-strange tau spectral data. We discuss the values o…
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…
Duality violations in tau hadronic spectral moments
D. R. Boito, O. Cata, M. Golterman +4
Evidence is presented for the necessity of including duality violations in a consistent description of spectral function moments employed in the precision determination of fr…
