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\rangle|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/\PsiJ/Ψ photoproduction transitions from exponential to power law at |t| \approx 1|t|≈1~GeV^22. This prediction could be tested at upcoming DIS facilities or in nucleus-proton ultraperipheral collisions (UPCs).
