New measurements of polarized valence and sea quark distributions of the nucleon in semi-inclusive deep inelastic scattering

OSTI ID:646412
We have measured semi-inclusive spin asymmetries for positively and negatively charged hadrons from polarized protons and deuterons and we have determined the polarized quark distributions {Delta}u{sub v}(x), {Delta}d{sub v}(x) and {Delta}{bar q}(x) of the valence and the non-strange sea quarks. Our results for the first moments of the polarized valence quark distributions are in good agreement with results obtained from the axial matrix elements {ital F} and {ital D}. The second moments are consistent with lattice QCD predictions. {copyright} {ital 1998 American Institute of Physics.}
