Dipole-Model Predictions of Gluon Saturation in Forward Jet and Vector Meson Production at the LHC

A color-dipole calculation that tests QCD gluon saturation at the LHC by combining an AAMQS dipole amplitude evolved with the nonlinear Balitsky-Kovchegov equation, IPSat impact-parameter dependence, and a stochastic nucleon-thickness lead profile. It predicts forward-dijet azimuthal decorrelation and exclusive J/psi and Upsilon photoproduction cross sections, and finds that Pb-Pb data favor saturating BK over linear BFKL evolution.
