Abstract
We present measurements of nucleon structure functions, F 2( ϰ, Q 2) and xFs( ϰ, Q 2), from the high-statistics, high-energy neutrino-iron scattering experiment at the Fermilab Tevatron. The existing high-statistics xF 3 determination by the CDHSW collaboration is compared to our data. The data presented here constitute the first corroboration of the QCD prediction of xF 3 evolution at low-ϰ, and yields Λ MS =210±28±41 MeV, and a determination of the GLS sum rule at Q 2 = 3 GeV 2, S GLS = ∫ ϰ 1 xF s ϰ =2.50±0.018 (stat.)±0.078 (syst.) . Our value of Λ MS yields α 3( M z ) = .111 ± .002 ± .003 ± .003 (scale). Comparison of the neutrino determination of F 2( ϰ, Q 2) with that obtained from the charged-lepton ( e or μ) scattering leads to a precise test of the mean-square charge prediction by the Quark Parton Model. The SLAC-CCFR and BCDMS structure function provide a consistent and precise set of structure functions over a large range of Q 2.
