چکیده
In this paper the exact analytical solution is found for the BFKL Pomeron calculus in QCD , in which all Pomeron loops have been included. This solution manifests the geometrical scaling behaviour and matches with the solution to the linear evolution equation on the line r2 = 1/Qs(x) where r is the dipole size and Qs is the saturation momentum.

A geometrical scaling solution to the BFKL Pomeron Calculus in the saturation domain
In this paper an analytical solution is found for the BFKL Pomeron calculus in QCD, in which all Pomeron loops have been included. This solution manifests the geometrical scaling behaviour and matches with the solution to the linear evolution equation on the line r2 = 1/Qs(x), where r is the dipole size and Qs is the saturation momentum.
متن کاملSumming Pomeron loops in the dipole approach
In this paper we argue that in the kinematic range given by 1 ≪ ln(1/αS) ≪ αS Y ≪ 1 αS , we can reduce the Pomeron calculus to the exchange of non-interacting Pomerons with the renormalized amplitude of their interaction with the target. Therefore, the summation of the Pomeron loops can be performed using the improved Mueller, Patel, Salam and Iancu approximation and this leads to the geometric...
متن کاملDiffusion into infra - red and unitarization of the BFKL pomeron
The BFKL pomeron in perturbative QCD is plagued by the lack of unitarity and diffusion into the infra-red region of gluon virtualities. These two problems are intimately related. We perform numerical studies of the evolution equation proposed by Balitsky and Kovchegov which unitarizes the BFKL pomeron. We show how diffusion into the infra-red region is suppressed due to the emergence of a satur...
متن کاملSolution for the BFKL Pomeron Calculus in zero transverse dimensions
In this paper the exact analytical solution is found for the BFKL Pomeron calculus in zero transverse dimensions, in which all Pomeron loops have been included. The comparison with the approximate methods of the solution is given, and the kinematic regions are discussed where they describe the behaviour of the scattering amplitude quite well. In particular, the semi-classical approach is consid...
متن کاملFluctuating pulled fronts & Pomerons
I give a physical discussion of the influence of particle number fluctuations on the high energy evolution in QCD. I emphasize the event–by–event description and the correspondence with the problem of ‘fluctuating pulled fronts’ in statistical physics. I show that the correlations generated by fluctuations reduce the phase–space for BFKL evolution up to saturation. Because of that, the evolutio...
