Description

I will first review the latest development in the nucleon spin structure study with lepton- nucleon deep inelastic scattering (DIS) from high energy laboratories. I will then concentrate on the progress and plan of study of the nucleon spin structure in the low energy region. With the newly built high luminosity 6 GeV electron beam accelerator and the progress in the highly polarized electron source and highly polarized targets, new experiments are being carried out at Jefferson Lab (CEBAF) to study the nucleon spin structure in the resonance region at low Q{sup 2}, with focus on the generalized GDH sum ... continued below

Description

I will first review the latest development in the nucleon spin structure study with lepton- nucleon deep inelastic scattering (DIS) from high energy laboratories. I will then concentrate on the progress and plan of study of the nucleon spin structure in the low energy region. With the newly built high luminosity 6 GeV electron beam accelerator and the progress in the highly polarized electron source and highly polarized targets, new experiments are being carried out at Jefferson Lab (CEBAF) to study the nucleon spin structure in the resonance region at low Q{sup 2}, with focus on the generalized GDH sum rule. Some preliminary results are presented. A generalized GDH sum rule study could provide a first comparison of experimental data with calculations from a fundamental theory over the entire Q{sup 2} regime. Taking advantage of the high luminosity of Jefferson Lab, selected spin structure experiments in the DIS region are also planned, concentrating in the valence quark region and the stud y of the quark-gluon correlations through higher twist effects. The parton-hadron duality provides the link between the DIS and the resonance region. Experimental study of duality in spin structure is planned. Outlook of spin structure study with a future 12 GeV energy upgraded Jefferson Lab is discussed.
