We show that quasi-elastic inclusive scattering data on light nuclei for medium Q^2 furnish information on $G_M^n$, whereas the deep-inelastic region for large $Q^2$ provides the Structure Function $F_2^n(x,Q^2)$. Common to the two…

Gribov theory is applied to investigate the shadowing effects in the structure functions of nuclei. In this approach these effects are related to the process of diffractive dissociation of a virtual photon. A model for this diffractive…
At small-x, the structure function F_L(x,Q2) is driven by the gluon content of the nucleon target and consequently it can unravel the underlying QCD dynamics in that region. In this work, one studies its behavior on photon virtuality Q2 at…
