چکیده
x 2 02 x 2 12 . These two dipoles then interact with the target. The non-linear term takes into account a simultaneous interaction of two produced dipoles with the target. The linear part of Eq. (1) is the LO BFKL equation, which describes the evolution of the multiplicity of the fixed size color dipoles with respect to the rapidity (energy) y. For the discussion below we introduce a short notation for the BK: d N d y = αs Ker ⊗ (N − N N) . The theoretical success associated with the BK is based on the following facts: • The BK is based on the correct high energy dynamics which is taken into account via the LO BFKL evolution kernel. • The BK restores the s-channel unitarity of partial waves (fixed

evolution equations in QCD † Anna
The following lectures are an introduction to the phenomena of partonic saturation and nonlinear evolution equations in Quantum Chromodynamics. After a short introduction to the linear evolution, the problems of unitarity bound and parton saturation are discussed. The nonlinear Balitsky-Kovchegov evolution equation in the high energy limit is introduced, and the progress towards the understandi...
متن کاملBalitsky’s hierarchy from Mueller’s dipole model and more about target correlations
High energy scattering is considered within the framework of the QCD dipole model formulated as a classical branching process. Starting from Mueller’s generating functional we derive the high energy evolution law for the scattering amplitude. The amplitude’s evolution is given by an infinite hierarchy of linear equations equivalent to Balitsky’s chain reduced to dipole operators. We comment abo...
متن کاملA Linear Evolution for Non-Linear Dynamics and Correlations in Realistic Nuclei
A new approach to high energy evolution based on a linear equation for QCD generating functional is developed. This approach opens a possibility for systematic study of correlations inside targets, and, in particular, inside realistic nuclei. Our results are presented as three new equations. The first one is a linear equation for QCD generating functional (and for scattering amplitude) that sum...
متن کاملSolution to the Balitsky-Kovchegov equation in the saturation domain
The solution to the Balitsky-Kovchegov equation is found in the deep saturation domain. The controversy between different approaches regarding the asymptotic behaviour of the scattering amplitude is solved. It is shown that the dipole amplitude behaves as 1− exp (−z + ln z) with z = ln(rQs) (r -size of the dipole, Qs is the saturation scale) in the deep saturation region. This solution is devel...
متن کاملLimiting fragmentation in hadron-hadron collisions at high energies
Limiting fragmentation in proton-proton, deuteron-nucleus and nucleusnucleus collisions is analyzed in the framework of the Balitsky-Kovchegov equation in high energy QCD. Good agreement with experimental data is obtained for a wide range of energies. Further detailed tests of limiting fragmentation at RHIC and the LHC will provide insight into the evolution equations for high energy QCD.
