Abstract
The experiment SANE (Spin Asymmetries of the Nucleon Experiment) measured inclusive double polarization electron asymmetries on a proton target at the Continuous Electron Beam Accelerator Facility at the Thomas Jefferson National Laboratory in Newport News Virgina. Polarized electrons were scattered from a solid 14 NH 3 polarized target provided by the University of Virginia target group. Measurements were taken with the target polarization oriented at 80 ◦ and 180 ◦ relative to the beam direction, and beam energies of 4.7 and 5.9 GeV were used. Scattered electrons were detected by a multi-component novel non-magnetic detector package constructed for this experiment. Asymmetries measured at the two target orientations allow for the extraction of the virtual Compton asymmetries A p 1 and A p 2 as well as the spin structure functions g p 1 and g2. p This work addresses the extraction of the virtual Compton asymmetry A p 1 in the deep inelastic regime. The analysis uses data in the kinematic range from Bjorken x of 0.30 to 0.55, separated into four Q 2 bins from 1.9 to 4.7 GeV 2 . Note: Abstract extracted from PDF text
