Phys. Rev. Lett. 81, 3595–3598 (1998)Measurement of αs(Q2) from the Gross–Llewellyn Smith Sum RuleReceived 8 May 1998; published in the issue dated 26 October 1998 We extract a set of values for the Gross–Llewellyn Smith sum rule at different values of 4-momentum transfer squared ( Q2), by combining revised CCFR neutrino data with data from other neutrino deep-inelastic scattering experiments for 1<Q2<15GeV2/c2. A comparison with the order αs3 theoretical predictions yields a determination of αs at the scale of the Z-boson mass of 0.114±0.0120.009. This measurement provides a new and useful test of perturbative QCD at low Q2, because of the low uncertainties in the higher order calculations. © 1998 The American Physical Society URL:
