Understand

Employing our previous framework to treat non-perturbative effects self-consistently, including duality violations, we update the determination of the strong coupling, \alpha_s, using a modified version of the 1998 OPAL data, updated to reflect current values of exclusive mode hadronic \tau decay branching fractions.

Our best n_f=3 values from the updated OPAL data are \alpha_s(m^2_\tau)=0.325+-0.018 and \alpha_s(m^2_\tau)=0.347+-0.025 in fixed-order and contour-improved perturbation theory, respectively.
To account for non-perturbative effects, non-linear, multi-parameter fits are necessary.
We have, therefore, investigated the posterior probability distribution of the model parameters underlying our fits in more detail.
