Spin asymmetries for exclusive and semi-exclusive reactions with CLAS

OSTI ID:842069
An extensive experimental program to measure the spin structure of the nucleons is being carried out with the CLAS detector at Jefferson Lab using a longitudinally polarized electron beam incident on a longitudinally polarized target. Spin degrees of freedom offer new tools to explore the baryon structure and test the many theoretical approaches that attempt to characterize it, such as effective Lagrangian models and transverse momentum dependent parton distributions. I will present preliminary results for single and double spin asymmetries for exclusive {pi}{sup 0}, {pi}{sup +}, and {eta} electroproduction in the resonance region compared with unitary isobar and dynamical models, as well as {rho} electroproduction for DIS kinematics. I will also report on an analysis of the semi-inclusive and exclusive channels where double and single spin asymmetries were used to study transverse momentum dependent parton distributions.
