The Spin Structure of the Proton in the Resonance Region
- Univ. of Virginia, Charlottesville, VA (United States)
Inclusive double spin asymmetries have been measured for $$\vec{p}$$($$\vec{e}$$,e') using the CLAS detector and a polarized 15NH3 target at Jefferson Lab in 1998. The virtual photon asymmetry A1, the longitudinal spin structure function, g1 (x, Q2), and the first moment Γ$$1\atop{p}$$, have been extracted for a Q2 range of 0.15-2.0 GeV2. These results provide insight into the low Q2 evolution of spin dependent asymmetries and structure functions as well as the transition of Γ$$1\atop{p}$$ from the photon point, where the Gerasimov, Drell and Hearn Sum Rule is expected to be satisfied, to the deep inelastic region.
