Title: Quark spin in the nucleon
Semi-inclusive deep inelastic scattering (SIDIS) experiments may be used to identify the flavor of the quark which participates in the scattering process. Semi-inclusive scattering identifies an electron scattering experiment in which the scattered electron and one hadron are detected in the final state. Longitudinally polarized hydrogen (15NH3) and deuterium (15ND3) targets and a longitudinally polarized electron beam have been used to investigate quark spin. The data was collected using the CEBAF Large Acceptance Spectrometer (CLAS) at Thomas Jefferson National Laboratory. The incident electron energy ranged between 1.6 GeV to 5.7 GeV. The electons impinged on either polarized proton or deuteron target. This work focuses on a kinematic region where the struck quark carries at least 30% of the nucleons total momentum (xb > 0.3). The leptons scatter mostly from valence quarks in this kinematic region allowing contributions from sea quarks to be neglected.
