Query: k_perp-factorization for Hard Processes on Nuclei in the Saturation
  Regime   We discuss applications of the recently developed nonlinear
k_perp--factorization for hard processes on nuclei. The starting point is the
color dipole approach which allows to introduce the concept of a collective
unintegrated nuclear gluon distribution. We focus on single--jet spectra, which
depend on the collective nuclear glue in a nonlinear manner. We briefly comment
on the Cronin effect.
