Nucleon Spin Structure Functions
Dorota Kotlorz
Abstract
The review of the nucleon spin structure functions problems is presented. The perturbative QCD predictions for the small x behaviour of the nucleon spin structure functions are discussed. The role of the resummation of the ln2 1/x terms is emphasized. Predictions for the nonsinglet structure function g1 in case of a flat as well as a dynamical input are given. The so called "spin crisis" on the context of both theoretical and experimental future hopes are also briefly discussed.
