JLAB Expt. E-03-109:“Spin Asymmetries on the Nucleon Experiment – SANE”

SANE Expt.:• Measure proton spin structure function (SSF) g2(x,Q2) and

spin asymmetries A1(x,Q2) at 2.5 ≤ Q2 ≤ 6.5 GeV2 and Bjorken x

(0.3 ≤ x ≤ 0.8).

spin asymmetries A1(x,Q2) at 2.5 ≤ Q2 ≤ 6.5 GeV2 and Bjorken x

(0.3 ≤ x ≤ 0.8).Physics Goals:

• Study x and Q2 dependence of SSF’s in poorly measured region.• Twist-3 effects from moments of g2 and g1.

• Comparison of Lattice QCD predictions of twist-3 matrix elements.• Exploration of “high x” region: A1 approach to x =1.• Test polarized local duality for final state mass W > 1.4 GeV.
