Description
High precision data in the Low-Q2 regime is crucial for the study of effective theories such as chiral perturbation theory, which collectively remain the best treatment of QCD in the non-perturbative regime. Measurements of the nucleon spin structure functions and their moments provide a very useful means to directly test the predictions of effective theories. The Jefferson Lab community has been highly active in experimentally measuring these spin structure functions in the low-Q2 regime for both the proton and neutron using inclusive electron scattering. In this talk I will discuss and review recent results from several completed low-Q2 spin structure experiments at Jefferson Lab. These results are compared to predictions of chiral perturbation theory at the level of moments and polarizabilities. I will also discuss future plans and prospects for the next generation of JLab spin structure experiments.
