We derive the general structure of the hadronic tensor required to describe deep-inelastic scattering from an off-shell nucleon within a covariant formalism. Of the large number of possible off-shellâ€¦ (More)

A re-analysis of data from NMC and SLAC leads to a great improvement in our knowledge of the valence d and u parton distribution functions at high x. Standard parton distributions with ourâ€¦ (More)

We calculate nuclear shadowing in lepton-deuteron deep inelastic scattering, which arises from the double scattering of the virtual photon from both nucleons in the deuteron. The total correction toâ€¦ (More)

The possible role played by vector mesons in inclusive deep inelastic lepton-nucleon scattering is investigated. In the context of the convolution model, we calculate self-consistently the scalingâ€¦ (More)

We discuss spin-dependent, deep-inelastic scattering from nuclei within a co-variant framework. In the relativistic impulse approximation this is described in terms of the amplitude for forward,â€¦ (More)

We study deep-inelastic scattering from polarized nuclei within a covariant framework. A clear connection is established between relativistic and non-relativistic limits, which enables a rigorousâ€¦ (More)

Recent data on the proton F2 structure function in the resonance region suggest that local quark-hadron duality works remarkably well for each of the low-lying resonances, including the elastic, toâ€¦ (More)
