Abstract
Nuclear deep inelastic structure functions \(F_{2}^{A}\)(x, Q2) as well as parton distribution functions in a nuclei are investigated in the framework of rescaling model. Our analysis is based on analytical expressions for quark and gluon densities in a proton derived at the leading order of QCD coupling. By fitting the rescaling parameters from the experimental data on \(F_{2}^{A}\)(x, Q2)/\(F_{2}^{D}\)(x, Q2) ratio for several nuclear targets, we derive predictions for corresponding nuclear parton distributions and, thus, for shadowing and antishadowing effects.
