"Nucleon Spin Physics Program in JLab's Hall C"
ABSTRACT:
The Hall C facility at Jefferson Lab is carrying out an extensive program of studies on nucleon spin physics, taking advantage of the CEBAF polarized electron beam and the versatile UVa polarized target. The program started in 2002 with a measurement of the longitudinal and transverse spin structure of the nucleon resonances in experiment 01-006 (Resonances Spin Structure - RSS) on proton and deuteron targets. This work is nearing publication of the final results for the proton, which will be presented. Preliminary results for the deuteron are available, too. The Spin Asymmetries on the Nucleon Experiment - SANE (E-03-109) is in preparation to extend the measurements of RSS and other experiments on the proton to higher momentum transfers. Going beyond inclusive polarized scattering, the Semi-SANE experiment (E-04-113) will detect scattered electrons and hadrons in coincidence, to determine the decomposition of the nucleon spin into its quark flavor components. Both SANE and Semi-SANE are scheduled to take data in 2008."
