The strong coupling from tau decays without prejudice
Diogo Boito, Maarten Golterman, Matthias Jamin +4
We review our recent determination of the strong coupling α_s from the OPAL data for non-strange hadronic tau decays. We find that α_s(m^2_τ) =0.325+-0.018 using fixed-order pertur…
Low-energy constants and condensates from the tau hadronic spectral functions
Diogo Boito, Maarten Golterman, Matthias Jamin +2
We use results of fits to the OPAL spectral data, obtained from non-strange hadronic τdecays, to evaluate the difference between the vector and axial current correlators, Π_{V-A}(Q…
An updated determination of α_s from tau decays
Diogo Boito, Maarten Golterman, Matthias Jamin +4
Employing our previous framework to treat non-perturbative effects self-consistently, including duality violations, we update the determination of the strong coupling, α_s, using a…
