The High Density Parton Dynamics from Eikonal and Dipole Pictures

TL;DR

This paper compares different theoretical approaches to high density QCD, demonstrating the equivalence of AGL and K methods, and proposing the AGL equation as a promising unitarized evolution equation in the double logarithmic approximation.

Contribution

It shows the equivalence between the AGL and K approaches and advocates for the AGL equation as a unitarized evolution equation in high density QCD.

Findings

AGL and K approaches are equivalent in high density QCD.

AGL equation is a good candidate for unitarized evolution at high densities.

Supports the use of AGL equation in the DLA limit.

Abstract

In this contribution we discuss distinct approaches for the high density QCD (hdQCD) and the demonstration of the equivalence between the AGL approach and the K approach is presented. Our conclusion is that the AGL equation is a good candidate for an unitarized evolution equation at high densities in the DLA limit.
