Sum Rules for Nucleon Spin Structure Functions
arXiv:hep-ph/9511264
Abstract
The uncertainties in the perturbative and higher twist corrections to the sum rules for are analyzed. The theoretical predictions for are compared with the whole set of experimental data and the restrictions on theoretical uncertainties was obtained. Suggestions for future experiments are given.
