The recent ALEPH measurements of the inclusive Cabibbo-suppressed decay width of the τ and several moments of its invariant mass distribution are used to determine the value of the strange quark mass. We obtain, in the MSbar scheme, ms(Mτ2) = (119±24) MeV to O(αs3), which corresponds to ms(1 GeV2) = (164±33) MeV, ms(4 GeV2) = (114±23) MeV.This work has been supported in part by the European Union TMR Network Eurodaphne (Contract No. ERBFMX-CT98-0169), by CICYT, Spain, under grants No. AEN-96/1672 and PB97-1261, and by Junta de Andalucí a Grant No. FQM-101Peer reviewedInstitute of Physics Publishing201120111999info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/33223reponame:DIGITAL.CSIC.
