The impact parameter dependence of color charge correlators in the proton isobtained from the light front formalism in light cone gauge. We include NLOcorrections due to the $|qqqg\rangle$ Fock state via light-cone perturbationtheory. Near the center of the proton, the $b$-dependence of the correlationsis very different from a "transverse profile function". The resulting$t$-dependence of exclusive $J/\Psi$ photoproduction transitions fromexponential to power law at $|t| \approx 1$ GeV$^2$. This prediction could betested at upcoming DIS facilities or in nucleus-proton ultraperipheralcollisions (UPCs).
