Neutron Structure Functions at Large $x$ from CLAS Measurements on Deuterium

ORAL

Abstract

The CLAS collaboration has measured inclusive structure functions in the resonance region and at large $x$ in electron scattering on polarized and unpolarized deuterium targets. In the unpolarized case, we have used a novel spectator tagging method to extract, for the first time, the neutron structure function $F_{2n(x,Q^2)}$ nearly free of kinematic smearing and nuclear model uncertainties. In the polarized case, the spin structure functions $g_1$ and $A_1$ of the neutron were extracted using a new unfolding procedure, yielding the first data of this kind in the resonance region. In this talk, the techniques employed will be discussed and the results of both experiments will be presented.
