Nuclear deep inelastic scattering is considered in the framework of a model in which the current operator explicitly satisfies Poincare invariance and current conservation. The results considerably differ from the standard ones at small…
Scaling studies of inclusive quasielastic electron scattering reactions have been used in the past as a basic tool to obtain information on the nucleon momentum distribution in nuclei. However, the connection between the scaling function,…

We analyze the proton and deuteron structure functions at large $x$ using a recently introduced scaling variable $\bar x$. This variable includes power corrections to $x$-scaling, and thus allows us to reach the Bjorken limit at moderate…
