Results from E07--013: Target Normal Single-Spin Asymmetry in Inclusive DIS

The target normal spin asymmetry $A_y$ in deep inelastic scattering is predicted to be exactly zero in the Born approximation. Recent theoretical calculations that assume two photon exchange with one quark give asymmetries of order $10^{-4}$, while calculations that assume the two photons couple to different quarks give asymmetries of order $10^{-2}$. The first measurement of this asymmetry on the neutron was made in Hall A at Jefferson Lab (E07-013) by the polarized $^3$He collaboration using an inclusive deep-inelastic $n^{\uparrow}(e,e')$ reaction with a vertically polarized $^3$He target and a 5.8 GeV electron beam. Results of this measurement will be presented and interpretations of the result will be discussed.
