Nuclear shadowing in a parton recombination model

Deep-inelastic structure functions ${\mathit{F}}_2^{\mathit{A}}$(x) are investigated in a ${\mathit{Q}}^2$ rescaling model with parton recombination effects. We find that the model can explain experimentally measured ${\mathit{F}}_2^{\mathit{A}}$(x) structure functions reasonably well in the wide Bjorken-x range (0.005<x<0.8). In the very small x region (x<0.02), recombination results are very sensitive to input sea-quark and gluon distributions.
