Abstract
We report recent results from Jefferson Lab Hall A “Neutron Transversity” experiment (E06-010). Transversely polarized target single-spin asymmetry AUT and beam-target double-spin asymmetry ALT have been measured in semi-inclusive deep-inelastic scattering (SIDIS) reactions on a polarized neutron (3He) target. Collins-type and Sivers-type asymmetries have been extracted from AUT for charged pion SIDIS productions, which are sensitive to quark transversity and Sivers distributions, correspondingly. Double spin asymmetry ALT is sensitive to a specific quark transverse momentum dependent parton distribution (TMD), the so-called “ transverse helicity” (g1T ) distributions. In addition, target singlespin asymmetries Ay in inclusive electron scattering on a transversely polarized 3He target in quasi-elastic and deep inelastic kinematics were also measured in Hall A.
