Abstract

We present studies of single-spin and double-spin asymmetries in semi-inclusive electroproduction of pions using the CEBAF 6 GeV polarized electron beam. Kinematic dependences of single and double spin asymmetries have been measured in a wide kinematic range at CLAS with a polarized NH3_3 target. Significant target-spin sin2ϕ\sin2\phi and sinϕ\sin\phi asymmetries have been observed. The hypothesis of factorization has been tested with zz-dependence of the double spin asymmetry.
