abstract
We generalize the Bartels-Ermolaev-Ryskin approach for the $g_1$ structure function at small-$x$ to determine the small-$x$ asymptotic behavior of the orbital angular momentum distributions in QCD. We present an exact analytical solution of the evolution equation in the double logarithmic approximation and discuss its implications for the proton spin problem.

Forward parton-nucleus scattering at next-to-eikonal accuracy in the CGC
Full next-to-eikonal quark and gluon propagators in a dynamical gluon background are derived, and forward quark and gluon production cross sections are computed for quark-nucleus and gluon-nucleus scattering.
