Results on the nucleon spin structure

Czechoslovak Journal of Physics Aims and scope

Abstract

SMC performed an investigation of the spin structure of the nucleon by measuring deep inelastic scattering of polarised mouns off polarised protons and deuterons: Asymmetries and spin structure functions were obtained for x>0.0008 and Q 2>0.2 GeV2. Using a next-to-leading order QCD analysis of all experimental results polarised parton distributions and their first moments were determined. All data show a clear violation of the Ellis-Jaffe sum rule. The Bjorken sum rule is found to be valid and is tested to the 10% level.
