Nuclear Shadowing in a Parton Recombination Model: Q${}^2$ Variation

Abstract

Q${}^2$ variation of the nuclear-structure-function ratio $F_2^A(x,Q^2)/F_2^D(x,Q^2)$ is investigated in a parton model with Q${}^2$-rescaling and parton-recombination effects. Calculated results are compared with the NMC (New Muon Collaboration) and the Fermilab-E665 experimental data. We find that our theoretical results show small Q${}^2$ variations and that they are consistent with the data within present experimental accuracy.
