The Proton's Spin Structure & Polarizabilities in the Strong QCD
Regime

Abstract: The proton's spin structure is still not well understood, especially in
the low Q^2 regime where the correlations between quarks becomes
significant. This talk will present the results of the E08-027 (g2p)
experiment, the first ever measurement of the proton's g2 structure
function in the low Q^2, strong QCD regime. This talk will also discuss
the experimental and analysis process of the experiment, and present
several Polarizabilities derived from the measured structure functions
which are directly compared to calculations of Chiral Perturbation Theory
and serve as a benchmark for future low Q^2 effective theories of QCD.
