We discuss the Wilson renormalization group approach to the effective action for low x physics. It is shown that in the linearized, weak field regime the RG equation reduces to the BFKL equation for… (More)

We continue the study of the effective action for low x physics based on a Wilson renormalization group approach. We express the full nonlinear renormalization group equation in terms of the average… (More)

In this paper we derive the complete Wilson renormalization group equation which governs the evolution of the gluon distribution and other gluonic observables at low x and arbitrary density.

Recent years have seen a growing activity centered around systems and experiments involving large numbers of partons. Experimental activities contributing to this newly focussed interest have been… (More)

We analyze the relation between evolution equations at low x that have been derived in different approaches in the last several years. We show that the equation derived by Balitsky and Kovchegov is… (More)

We analyze the general nonlinear evolution equations for multi gluon correlators derived in [1] by restricting ourselves to a double logarithmic region. In this region our evolution equation becomes… (More)

We compute the distribution functions for gluons at very small x and not too large values of transverse momenta. We extend the McLerranVenugopalan model by using renormalization group methods to… (More)

We study the inclusion of running coupling corrections into the non-linear small-x JIMWLK and BK evolution equations by resumming all powers of αsNf in the evolution kernels. We demonstrate that the… (More)
