Off-shell corrections and moments of the deep inelastic nuclear structure functions

We present an improved method of handling off-shell effects in deep inelastic nuclear scattering. With a firm understanding of the effects of the nuclear wavefunction, including these off-shell corrections as well as binding effects and nucleon-nucleon correlations, we can begin to examine the role of QCD in nuclei through an analysis of the moments of the nuclear inelastic structure function F2A. Our analysis is aimed on one side at extracting the Q2 dependence of the moments of the nucleon structure function by using the recent high x world Iron data and by properly subtracting nuclear effects from the perturbative contribution. On the other side we compare quantitatively the behavior of the extracted moments with a simple O(1/Q2) phenomenological form and we determine the mass term for this parametrization.
