title: Nonuniversality aspects of nonlinear k(perpendicular) factorization for hard dijets.
abstract: The origin of breaking of conventional linear k(perpendicular) factorization for hard processes in a nuclear environment is by now well established. The realization of the nonlinear nuclear k(perpendicular) factorization which emerges instead was found to change from one jet observable to another. Here we demonstrate how the pattern of nonlinear k(perpendicular) factorization, and especially the role of diffractive interactions, in the production of dijets off nuclei depends on the color properties of the underlying pQCD subprocess.
