摘要：

Color charge correlations in the proton at moderately small x similar to 0.1 are extracted from its light-cone wave function. The charge fluctuations are far from Gaussian and they exhibit interesting dependence on the impact parameter and on the relative transverse momentum (or distance) of the gluon probes. We provide initial conditions for small-x Balitsky-Kovchegov evolution of the dipole scattering amplitude with impact parameter and (r) over cap center dot (b) over cap dependence, and with a nonzero C-odd component due to three-gluon exchange. Lastly, we compute the (forward) Weizsacker-Williams gluon distributions, including the distribution of linearly polarized gluons, up to fourth order in A(+). The correction due to the quartic correlator provides a transverse momentum scale, q greater than or similar to 0.5 GeV, for nearly maximal polarization.
