Progress in experimental studies on longitudinal spin structure of nucleon
摘要
Abstract
This paper presents the progress on the study of the longitudinal spin structure functions of nucleon. First, we describe a few theories on spin structure, including naive parton model and the quark-parton model in the QCD. At same time, we introduce the scaling rule and the reason of its violation. The basic theories for the experimental study are then explained, including the roles of axis currents in the weak interaction and deep inelastic scattering of lepton-nucleon, and several sum rules of spin structure function of nucleon and their QCD correction. Second, we discuss the experimental methods on measurement of cross sections asymmetry in the deep inelastic scattering(DIS), including inclusive, semi-inclusive, and exclusive measurements. At last, various kinds of experimental studies and their characteristics from major laboratories around the world and their results in the last forty years are described in details in this article.关键词
