MEASUREMENT OF ALPHA(S)(Q(2)) FROM THE GROSS-LLEWELLYN-SMITH SUM-RULE

We extract a set of values for the Gross-Llewellyn Smith sum rule at d ifferent values of 4-momentum transfer squared (Q(2)), by combining re vised CCFR neutrino data with data from other neutrino deep-inelastic scattering experiments for 1 < Q(2) < 15 GeV2/c(2). A comparison with the order alpha(s)(3) theoretical predictions yields a determination o f ct, at the scale of;he Z-boson mass of 0.114 +/- (0.009)(0.012). Thi s measurement provides a new and useful test of perturbative QCD at lo w Q(2), because of the low uncertainties in the higher order calculati ons. [S0031-9007(98)07266-4].
