Description:
Author(s): Diogo Boito, Maarten Golterman, Kim Maltman, James Osborne, and Santiago Peris We apply an analysis method previously developed for the extraction of the strong coupling from the OPAL data to the recently revised ALEPH data for nonstrange hadronic τ decays. Our analysis yields the values α s (m τ 2 )=0.296±0.010 using fixed-order perturbation theory, and α s (m τ 2 )=0.310±0.014 using c... [Phys. Rev. D 91, 034003] Published Tue Feb 03, 2015
