Abstract
The impact parameter dependence of color charge correlators in the proton is obtained from the light front formalism in light cone gauge. We include NLO corrections due to the |qqqg⟩|qqqg⟩ Fock state via light-cone perturbation theory. Near the center of the proton, the bb-dependence of the correlations is very different from a "transverse profile function". The resulting tt-dependence of exclusive J/ΨJ/Ψ photoproduction transitions from exponential to power law at |t|≈1|t|≈1 GeV22. This prediction could be tested at upcoming DIS facilities or in nucleus-proton ultraperipheral collisions (UPCs).
