However, the proton spin structure function, <br>$g_{2}^{p}$, has not. <br>Recently an experiment (E08-027, also named G2P) is carried out at Jefferson Lab Hall A <br>to measure the proton $g_2$ structure function in the low momentum transfer region covering <br>$0.02 < Q^2 < 0.20 \space (GeV^2)$. <br>This experiment allows us not only to extract the generalized longitudinal-transverse spin polarizability ($\delta^{LT}$) <br>then give a benchmark test to the Chiral Perturbation Theory ($\chi^{PT}$) in this kinematic region, <br>but also test the Burkhardt-Cottingham sum rule at low $Q^2$. <br>The details of the experiment and the preliminary results will be present.<br clear="all"><br>============================================<br clear="all">Tex code end.<br>-- <br><div class="gmail_signature" data-smartmail="gmail_signature">With Best Regards,<br>Jixie Zhang<br>757-269-7735 <br>_______________________________________________</div>
