Next-to-leading order analysis of target mass corrections to structure functions and asymmetries

We perform a comprehensive analysis of target mass corrections to spin-averaged structure functions and asymmetries at next-to-leading order. Several different prescriptions for target mass corrections are considered, including the operator product expansion, and various approximations to it, collinear factorization, and xi-scaling. We assess the impact of each of these on a number of observables, such as the neutron to proton F-2 structure function ratio, and parity-violating electron scattering asymmetries for protons and deuterons which are sensitive to gamma Z interference effects. The corrections from higher order radiative and nuclear effects on the parity-violating deuteron asymmetry are also quantified.
