Deuteron spin structure functions in the resonance and deep inelastic scattering regions

Abstract

We derive relations between spin-dependent nuclear and nucleon ${g}_{1}$ and ${g}_{2}$ structure functions within the nuclear impulse approximation, which are valid at all ${Q}^{2}$, and in both the resonance and deep inelastic regions. We apply the formalism to the specific case of the deuteron, which is often used as a source of neutron structure information, and compare the size of the nuclear corrections calculated using exact kinematics and using approximations applicable at large ${Q}^{2}$.
