Title: Rapidity gap distribution in diffractive deep-inelastic scattering and parton genealogy

Abstract

We propose a partonic picture for high-mass diffractive dissociation events in onium-nucleus scattering, which leads to simple and robust predictions for the distribution of the sizes of gaps in diffractive dissociation of virtual photons off nuclei at very high energies. We show that the obtained probability distribution can formally be identified to the distribution of the decay time of the most recent common ancestor of a set of objects generated near the edge of a branching random walk, and explain the physical origin of this appealing correspondence. We then use the fact that the diffractive cross section conditioned to a minimum rapidity gap size obeys a set of Balitsky-Kovchegov equations in order to test numerically our analytical predictions. Furthermore, we show how simulations in the framework of a Monte Carlo implementation of the QCD evolution support our picture.

Nuclear scattering configurations of onia in different frames

Journal Article Le, Anh Dung ; Mueller, Alfred H. ; Munier, Stéphane - Physical Review D

In the scattering of a small onium off a large nucleus at high center-of-mass energies, when the parameters are set in such a way that the cross section at a fixed impact parameter is small, events are triggered by rare partonic fluctuations of the onium, which are very deformed with respect to typical configurations. Using the color dipole picture of high-energy interactions in quantum chromodynamics, in which the quantum states of the onium are represented by sets of dipoles generated by a branching process, we describe the typical scattering configurations as seen from different reference frames, from the rest framemore »« less

Analytical asymptotics for hard diffraction

Journal Article Le, Anh Dung ; Mueller, Alfred H. ; Munier, Stéphane - Physical Review. D.

We show that the cross section for diffractive dissociation of a small onium off a large nucleus at total rapidity and requiring a minimum rapidity gap Y_gap can be identified, in a well-defined parametric limit, with a simple classical observable on the stochastic process representing the evolution of the state of the onium, as its rapidity increases, in the form of color dipole branchings: it formally coincides with twice the probability that an even number of these dipoles effectively participate in the scattering, when viewed in a frame in which the onium is evolved to the rapidity Y – Y_gap.more »« less

Rapidity evolution of the entanglement entropy in quarkonium: Parton and string duality

Journal Article Liu, Yizhuang ; Nowak, Maciej A. ; Zahed, Ismail - Physical Review D

We investigate the quantum entanglement in rapidity space of the soft gluon wave function of a quarkonium in theories with nontrivial rapidity evolutions. We found that the rapidity evolution drastically changes the behavior of the entanglement entropy, at any given order in perturbation theory. At large � � , the reduced density matrices that “resum” the leading rapidity logs can be explicitly constructed, and shown to satisfy Balitsky-Kovchegov-like evolution equations. We study their entanglement entropy in a simplified 1 + 1 toy model and in 3D QCD. The entanglement entropy in these cases, after resummation, is shown to saturate themore »« less

Generalized parton distributions and rapidity gap survival in exclusive diffractive pp scattering

Journal Article Frankfurt, Leonid ; Hyde-Wright, Charles ; Strikman, Mark ; ... - Phys.Rev.D

We propose a new approach to the problem of rapidity gap survival (RGS) in the production of high-mass systems (H = dijet, heavy quarkonium, Higgs boson) in double-gap exclusive diffractive pp scattering, pp-->p + (gap) + H + (gap) + p. It is based on the idea that hard and soft interactions proceed over widely different time- and distance scales and are thus approximately independent. The high-mass system is produced in a hard scattering process with exchange of two gluons between the protons. Its amplitude is calculable in terms of the gluon generalized parton distributions (GPDs) in the protons, whichmore »« less

Transverse momentum dependent parton distributions at small-x

Journal Article Xiao, Bo-Wen ; Yuan, Feng ; Zhou, Jian - Nuclear Physics. B

We study the transverse momentum dependent (TMD) parton distributions at small-x in a consistent framework that takes into account the TMD evolution and small-x evolution simultaneously. The small-x evolution effects are included by computing the TMDs at appropriate scales in terms of the dipole scattering amplitudes, which obey the relevant Balitsky–Kovchegov equation. Meanwhile, the TMD evolution is obtained by resumming the Collins–Soper type large logarithms emerged from the calculations in small-x formalism into Sudakov factors.
