Description
Color charge correlations in the proton at moderately small x
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.
This analysis provides initial conditions for small-x
Balitsky-Kovchegov evolution of the dipole scattering amplitude which
include impact parameter and r*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 the EIC. They also determine
unintegrated gluon distributions of the proton relevant for
gamma - p, p - p, and p - A collisions.
