Description
The three point light-cone correlation function of color charge densities is evaluated in light-cone gauge. The proton is approximated as a non-perturbative 3-quark state plus perturbative corrections due to the emission of a gluon which is not required to be soft. The resulting expressions provide the C-odd contribution to the initial conditions for high-energy evolution of the dipole scattering amplitude to small x.
We also present numerical estimates for the perturbative 3-gluon exchange amplitude (hard Odderon) as a function of dipole size, impact parameter, their relative azimuthal angle, and light-cone momentum cutoff x. We find that this amplitude increases as x decreases from 0.1 to 0.01. At yet lower x, the reversal of this energy dependence would reflect the onset of universal small-x renormalization group evolution.
