Description
Values of the strong coupling constant, αs, from the fit to the scaling violation of nucleon structure functions, F2 and xF3, and from the Gross-Llewellyn-Smith sum rule are presented. The resulting value of ΛM-barS-bar(4),NLO from the combined systematic fit on both F2 and xF3 from the CCFR experiment is 331 ± 24(exp) ± 13(HT) MeV which results the value of αs at Q2 = MZ2 of 0.119 ± 0.002(exp) ± 0.001(HT) ± 0.004(Scale). The preliminary value of αsNNLO(MZ2) from the GLS sum-rule analysis is 0.112-0.013+0.011(combined). These values are consistent with each other within their uncertainties and are in good agreement with other measurements of αs. (author)
