Solution 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 کاملHigh Energy Evolution beyond the Balitsky - Kovchegov Equation
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 nota...
متن کاملOn solutions of the Balitsky - Kovchegov equation with impact parameter
We numerically analyze the Balitsky-Kovchegov equation with the full dependence on impact parameter b. We show that due to a particular b-dependence of the initial condition the amplitude decreases for large dipole sizes r. Thus the region of saturation has a finite extension in the dipole size r, and its width increases with rapidity. We also calculate the b-dependent saturation scale and disc...
متن کاملTraveling waves and the renormalization group improved Balitsky–Kovchegov equation
I study the incorporation of renormalization group (RG) improved BFKL kernels in the Balitsky–Kovchegov (BK) equation which describes parton saturation. The RG improvement takes into account important parts of the next-to-leading and higher order logarithmic corrections to the kernel. The traveling wave front method for analyzing the BK equation is generalized to deal with RG-resummed kernels, ...
متن کاملImpact Parameter Dependence in the Balitsky-Kovchegov Equation
We study the impact parameter dependence of solutions to the Balitsky-Kovchegov (BK) equation. We argue that if the kernel of the BK integral equation is regulated to cutoff infrared singularities, then it can be approximated by an equation without diffusion in impact parameter. For some purposes, when momentum scales large compared to ΛQCD are probed, the kernel may be approximated as massless...
