Title: Subfemtometer scale color charge correlations in the proton

Abstract

Color charge correlations in the proton at moderately small x~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^·b^ dependence, and with a nonzero C-odd component due to three-gluon exchange. Lastly, we compute the (forward) Weizsäcker-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≳0.5 GeV, for nearly maximal polarization.

BFKL Pomeron loop contribution in diffractive photoproduction and inclusive hadroproduction of J/ψ and Υ

Journal Article Kotko, Piotr ; Motyka, Leszek ; Sadzikowski, Mariusz ; ... - Journal of High Energy Physics (Online)

We analyze contributions to the heavy vector meson production with large transverse momentum in proton-proton and diffractive photon-proton scattering driven by an exchange of two Balitsky-Fadin-Kuraev-Lipatov Pomerons in the squared amplitudes. The Pomerons couple to a single parton and form a Pomeron loop closed by the vector meson impact factors. For the photon-proton case the diffractive cut of the Pomeron loop contributes, and for the inclusive hadroproduction one finds the loop with two cut Pomerons. We compute both of these Pomeron loop contributions and study in detail their properties. The results are then used to calculate the cross sections formore »« less

Color charge correlations in the proton at NLO: Beyond geometry based intuition

Journal Article Dumitru, Adrian ; Mäntysaari, Heikki ; Paatelainen, Risto - Physics Letters B

Color charge correlators provide fundamental information about the proton structure. In this Letter, we evaluate numerically two-point color charge correlations in a proton on the light cone including the next-to-leading order corrections due to emission or exchange of a perturbative gluon. The non-perturbative valence quark structure of the proton is modelled in a way consistent with high-x proton structure data. Our results show that the correlator exhibits startlingly non-trivial behavior at large momentum transfer or central impact parameters, and that the color charge correlation depends not only on the impact parameter but also on the relative transverse momentum of themore »« less
