Description
Color charge correlations in the proton at moderately small x are extracted from its light-cone wave function. Charge fluctuations are far from Gaussian and the correlators exhibit non-trivial dependence on impact parameter as well as on the relative transverse momentum (or distance) of the gluon probes.
This analysis also 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 the physics of p - p, and p - A collisions, e.g. for understanding the initial state.
