摘要
This paper will present a survey of recent experimental results for the g(1) and g(2) spin structure functions. Over the past decade, these structure functions (and the virtual photon asymmetries A(1) and A(2)) have been well-measured in the large-Q(2) scaling region using inclusive polarized deep-inelastic scattering. New precision results from Jefferson Lab are now becoming available which cover kinematic regions that were previously poorly measured or completely unmeasured. Topics covered will include: recent experiments at Jefferson Lab which have made precise measurements of g(1) in the resonance region for both proton and neutron to investigate the Q(2) evolution of the GDH sum rule, a new measurement of A(1) for the neutron in the large-x region where valence quark dynamics dominate, new precision results for g(2) from Jefferson Lab, a review of the g(1) results and NLO analyses in the scaling region for the SLAC, HERMES, and SMC data. Finally, a survey of results expected from several new experiments and longer-term experimental programs are discussed.
