An Analysis of the Asymptotic Limit of Gluon Shadowing
  We examine the gluon distributions in nuclei in the asymptotic region defined by $Q^2 \to \infty$, $x \to 0$. An analysis using the Double Asymptotic Scaling variables of Ball and Forte is proposed. New scaling relations are predicted which can help disentangling the different mechanisms of low $x$ perturbative QCD evolution in nuclei.
