New Measurements of the Target-normal Single-spin Asymmetry $A_y$ for $^3$He$^\uparrow (e,e^\prime)$ in Quasi-elastic and Deep-inelastic Scattering

Results from recent measurements of the target single spin asymmetry (SSA) in $^3$He$^\uparrow (e,e^\prime) $ from $^3$He nuclei polarized normal to the lepton scattering plane. For both elastic scattering and deep-inelastic scattering, this asymmetry, $A_y$, is exactly zero for one-photon exchange. However, it can be non-zero when two-photon exchange is included. For elastic scattering, a large, negative asymmetry with statistical precision 8-10$\sigma$ was recently measured for the first time at Jefferson Lab using an SEOP polarized $^3$He target. At $Q^2\sim1$ GeV$^2$ the asymmetry can be related to moments of the GPDs. Our result is in agreement with a prediction based on a GPD-model and thus provides new, independent constraints on these distributions. In deep-inelastic scattering, a large, positive (neutron) asymmetry was also observed and agreed well with model predictions using the ``Sivers'' distribution obtained from SIDIS transversely measurements. Finally, results will be presented for $^3$He$^\uparrow (e,e^\prime n)$ which at low $Q^2$ is highly dependent on the wave function of the polarized $^3$He nucleus.
