Comparison of moments from the valence structure function with QCD predictions

1979

Abstract We present moments (both ordinary and Nachtmann) of the nucleon valence structure function measured in high Q 2 ν FE scattering, supplemented by data from deep inelastic eD scattering. These data seem to agree with QCD predictions for vector gluons. The QCD parameter Λ is found to be of the order 0.5 GeV.
