Description
Color charge correlations in the proton at moderately small $x \sim 0.1$
are extracted from its light-cone wave function. The charge
fluctuations are far from Gaussian. Correlators are described by
n-body GPDs which exhibit interesting dependence on impact parameter
as well as on the relative transverse momentum (or distance) of the
gluon probes.
Furthermore, this analysis provides initial conditions for small-$x$
Balitsky-Kovchegov evolution of the dipole scattering amplitude which
include impact parameter and $\hat{r}\cdot\hat{b}$ dependence, and with non-zero $C$-odd
component due to three-gluon exchange.
The color charge correlators could be measured through various
exclusive processes at a high-luminosity EIC.
