Dipole-dipole scattering amplitude in the CGC approach

چکیده
In this paper we propose recurrence relations for the dipole densities in QCD, which allows us to find these from solution BFKL equation. We resolve diffusion approximation kernel. Based on solution, found sum of large Pomeron loops. This generates scattering amplitude that decreases at values rapidity $Y$. It turns out such behaviour amplitudes is an artifact approximation. leads unitarization without saturation both deep inelastic and dipole-dipole interaction high energies.

Dipole Scattering Amplitude in Momentum Space: Investigating Fluctuations at HERA
We extend a recently proposed dipole model which relates the virtual photon-proton cross section to the dipole-proton forward scattering amplitude in momentum space investigating the effects of the gluon number fluctuations. The model interpolates between well known asymptotic behaviours predicted by perturbative QCD from the Balitsky-Kovchegov equation, which describes the rapidity evolution o...
متن کاملHigh–energy Hadron–hadron (dipole–dipole) Scattering from Lattice Qcd
In this paper the problem of the high–energy hadron–hadron (dipole–dipole) scattering is approached (for the first time) from the point of view of lattice QCD, by means of Monte Carlo numerical simulations. In the first part, we give a brief review of how high– energy scattering amplitudes can be reconstructed, using a functional integral approach, in terms of certain correlation functions of t...
متن کاملQuasielastic Scattering in the Dipole Model
A series of previous papers [1] develops a dipole model in initial state impact parameter space that includes subleading effects such as running αs, unitarity, confinement and saturation. Here some recent work [2] is presented, where the model is applied to a new set of data: vector meson production in γp, DVCS and dσ/dt in pp. This allows us to tune a more realistic model of the proton wavefun...
متن کاملHigh Energy Scattering in Qcd: Dipole Approach with Pomeron Loops
The simplest approach that we can propose for high energy interaction is based 1,2 on the BFKL Pomeron 3 and reggeon-like diagram technique for the BFKL Pomeron interactions . This technique which is a generalization of Gribov Reggeon Calculus , can be written in the elegant form of the functional integral (see Ref. 5 and the next section); and it is a challenge to solve this theory in QCD find...
متن کاملDipole scattering in highly polar semiconductor alloys
The wide gap polar semiconductors III-V nitrides, II-VI oxides, and ferroelectrics exhibit large spontaneous and piezoelectric polarization due to their nonsymmetric crystal structures. Electrical conductivity in alloys of such crystals is degraded by scattering from the varying polarization coupled to alloy disorder. We have modeled this effect by dipole scattering. We have calculated dipole s...
