  • Description: The origin of breaking of conventional linear k(perpendicular to) factorization for hard processes in a nuclear environment is by now well established. The realization of the nonlinear nuclear k(perpendicular to) factorization which emerges instead was found to change from one jet observable to another. Here we demonstrate how the pattern of nonlinear k(perpendicular to) 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.
