</span></b><span style="font-size:12.0pt;line-height:105%;font-family:"Times New Roman",serif">The proton's spin structure is still not well understood, especially in<br>
the low Q^2 regime where the correlations between quarks becomes<br>
significant. This talk will present the results of the E08-027 (g2p)<br>
experiment, the first ever measurement of the proton's g2 structure<br>
function in the low Q^2, strong QCD regime. This talk will also discuss<br>
the experimental and analysis process of the experiment, and present<br>
several Polarizabilities derived from the measured structure functions<br>
which are directly compared to calculations of Chiral Perturbation Theory<br>
and serve as a benchmark for future low Q^2 effective theories of QCD.</span><o:p></o:p></p>
