The early stages of heavy ion collisions are dominated by high density systems of gluons
that carry each a small fraction x of the momenta of the colliding nucleons. A distinguishing …

A bstract We propose the eikonal approximation as a simple and reliable tool to analyze
relativistic high-energy processes, provided that the necessary subtleties are accounted for …

When hadrons scatter at high energies, strong color fields, whose dynamics is described by
quantum chromodynamics (QCD), are generated at the interaction point. If one represents …

We construct the effective Hamiltonian which governs the renormalization group flow of the
gluon distribution with increasing energy and in the leading logarithmic approximation. This …

Within the limits of the large-Nc approximation (with Nc the number of colors), we establish
the high-energy behaviour of the diffractive and inclusive cross-sections for deep inelastic …

An effective non-local quantum field theory is constructed, which describes the interaction of
pomerons in high-colored QCD. The theory includes both splitting and merging triple …

We reinterpret the JIMWLK/KLWMIJ evolution equation as the QCD Reggeon field theory
(RFT). The basic" quantum Reggeon field" in this theory is the unitary matrix R which …

We develop the formalism for calculating semi-inclusive observables at high energy in the
JIMWLK/KLWMIJ approach. This approach is valid for scattering of a small perturbative …

We analyze a toy model which has a structure similar to that of the recently found QCD
evolution equations, but without transverse dimensions. We develop two different but …

We explore the properties of the QCD high energy evolution in the limit of a dilute target.
Using the recently established property of self-duality of the evolution operator, we show …
