Query: Cubic color charge correlator in a proton made of three quarks and a
  gluon   The three point correlation function of color charge densities is evaluated
explicitly in light cone gauge for a proton on the light cone. This includes
both $C$-conjugation even and odd contributions. We account for perturbative
corrections to the three-quark light cone wave function due to the emission of
an internal gluon which is not required to be soft. We verify the Ward identity
as well as the cancellation of UV divergences in the sum of all diagrams so
that the correlator is independent of the renormalization scale. It does,
however, exhibit the well known soft and collinear singularities. The
expressions derived here provide the $C$-odd contribution to the initial
conditions for high-energy evolution of the dipole scattering amplitude to
small $x$. Finally, we also present a numerical model estimate of the impact
parameter dependence of quantum color charge three-point correlations in the
proton at moderately small $x$.
