Strange quark mass dependence of the tau hadronic width

Description

The perturbative quark mass corrections to the tau hadronic width are studied to O(α3s m2q). Including up to dimension four corrections, we get ms(4 GeV2) = (143 ± 42) MeV [ms(1 GeV2) = (193 ± 59) MeV]. Possible improvements to reduce the theoretical uncertainty are pointed out
