  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 $|qqqg\rangle$ Fock state via light-cone perturbation
theory. Near the center of the proton, the $b$-dependence of the correlations
is very different from a "transverse profile function". The resulting
$t$-dependence of exclusive $J/\Psi$ photoproduction transitions from
exponential to power law at $|t| \approx 1$ GeV$^2$. This prediction could be
tested at upcoming DIS facilities or in nucleus-proton ultraperipheral
collisions (UPCs).
