Op. Solovtsova, ROLE OF THE ANALYTICITY OF THE QCD COUPLING-CONSTANT IN THE DESCRIPTION OF THE INCLUSIVE DECAY OF A TAU-LEPTON INTO HADRONS, JETP letters, 64(10), 1996, pp. 714-717
The role of the analyticity of the running QCD coupling constant in th
e description of the inclusive decay of a tau lepton into hadrons is i
nvestigated. It is shown that the analyticity of the coupling constant
strongly influences the values extracted for both alpha(s) and the pa
rameter Lambda from the experimental data on tau decay. (C) 1996 Ameri
