αs from the (revised) ALEPH data for τ decay
چکیده انگلیسی

We present a new analysis of αs from hadronic τ decays based on the recently revised ALEPH data, employing a strategy previously applied to the OPAL data. We examine critically the approach traditionally used, comparing it to our strategy, and commenting on the main differences between the two. Our analysis yields the values using fixed-order perturbation theory, and using contour-improved perturbation theory. Averaging these values with our previously obtained values from the OPAL data, we find , respectively, , as the most reliable results for αs from τ decays currently available.
