Polarized Quarks, Gluons and Sea in Nucleon Structure Functions

概要

We perform a NLO analysis of polarized deep inelastic scattering date to test two different solutions to the so-called spin crisis, one of them based on the axial gluon anomaly and consistent with the Bjorken sum rule, and another in which the defects in the spin sum rules and in the Gottfried sum rule are related. In this case a defects is also expected for the Bjorken sum rule. The first solution is slightly favoured by the SLAC E154 results, but both options seem to be consistent with the CERN SMC date.
