αₛ from the (revised) ALEPH data for τ decay

Original · EN

We present a new analysis of αₛ from hadronic τ decays based on the recently revised ALEPH data. The analysis is based on a strategy which we previously applied to the OPAL data. We critically compare our strategy to the one traditionally used and comment on the main differences. Our analysis yields the values αₛ(mτ²)=0.296± 0.010 using fixed-order perturbation theory, and αₛ(mτ²)=0.310± 0.014 using contour-improved perturbation theory. Averaging these values with our previously obtained values from the OPAL data, we find αₛ(mτ²)=0.303± 0.009, respectively, αₛ(mτ²)=0.319± 0.012, as the most reliable results for αₛ from τ decays currently available.
