Query: A new evolution equation   We propose a new evolution equation for the gluon density relevant for the
region of small $x_B$. It generalizes the GLR equation and allows deeper
penetration in dense parton systems than the GLR equation does. This
generalization consists of taking shadowing effects more comprehensively into
account by including multigluon correlations, and allowing for an arbitrary
initial gluon distribution in a hadron. We solve the new equation for fixed
$\alpha_s$. We find that the effects of multigluon correlations on the
deep-inelastic structure function are small.
