Spin Structure in the Resonance Region

ORAL

Abstract

The RSS collaboration has measured the spin structure functions of the proton and the deuteron at Jefferson Lab using the lab's polarized electron beam, the Hall~C HMS spectrometer and the UVa polarized solid target. The asymmetries $A_{\|}$ and $A_{\perp}$ were measured at the elastic peak and in the region of the nucleon resonances ($0.70 \; \mathrm{GeV} < W < 1.98 \; \mathrm{GeV}$) at an average four momentum transfer of $Q^2 = 1.3 \; \mathrm{GeV}^2$. The extracted spin structure functions and their kinematic dependence make a significant contribution in the study of higher-twist effects and polarized duality tests.
