AbstractThe perturbative quark-mass corrections to the τ hadronic width are analysed to O(αs3mq2), using the presently available theoretical information. The behaviour of the perturbative series is investigated in order to assess the associated uncertainties. The implications for the determination of the strange quark mass from τ decay data are discussed.
