OFF-SHELL CORRECTIONS AND MOMENTS OF THE DEEP-INELASTIC NUCLEAR-STRUCTURE FUNCTIONS

We present an improved method of handling off-shell effects in deep in elastic nuclear scattering. With a firm understanding of the effects o f the nuclear wavefunction, including these off-shell corrections as w ell as binding effects and nucleon-nucleon correlations, we can begin to examine the role of QCD in nuclei through an analysis of the moment s of the nuclear inelastic structure function F-2(A). Our analysis is aimed on one side at extracting the Q(2) dependence of the moments of the nucleon structure function by using the recent high x world Iron d ata 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/Q(2)) phenomenological for m and we determine the mass term for this parametrization.
