Consequences of strong fluctuations on high-energy QCD evolution

C. Marquet, R. Peschanski, G. Soyez

We investigate the behaviour of the QCD evolution towards high-energy, in the diffusive approximation, in the limit where the fluctuation contribution is large. Our solution for th…

General analysis of polarization phenomena in for axial parametrization of two--photon exchange

G. I. Gakh, E. Tomasi-Gustafsson

General properties of the differential cross section and of the polarization observables are derived for the reaction, in presence of two--photon exchange. Po…

Traveling waves in high energy QCD

Robi Peschanski

Saturation is expected to occur when a high density of partons (mainly gluons)- or equivalently strong fields in Quantum Chromodynamics (QCD) - is realized in the weak coupling reg…

Particle production and saturation at HERA

Cyrille Marquet

Perturbative QCD in the high-energy limit describes the evolution of scattering amplitudes with increasing energy towards and into the so-called saturation regime. Comparisons of t…

On the Probabilistic Interpretation of the Evolution Equations with Pomeron Loops in QCD

E. Iancu, G. Soyez, D. N. Triantafyllopoulos

We study some structural aspects of the evolution equations with Pomeron loops recently derived in QCD at high energy and for a large number of colors, with the purpose of clarifyi…

QCD traveling waves at non-asymptotic energies

C. Marquet, R. Peschanski, G. Soyez

Using consistent truncations of the BFKL kernel, we derive analytical traveling-wave solutions of the Balitsky-Kovchegov saturation equation for both fixed and running coupling. A…

Infrared instability from nonlinear QCD evolution

R. Enberg, R. Peschanski

Using the Balitsky-Kovchegov (BK) equation as an explicit example, we show that nonlinear QCD evolution leads to an instability in the propagation toward the infrared of the gluon…

Small-x QCD effects in forward-jet and Mueller-Navelet jet production

C. Marquet, C. Royon

We investigate small-x QCD effects in forward-jet production in deep inelastic scattering in the kinematic regime where the virtuality of the photon and the transverse momentum of…

The Problem of Mass: Mesonic Bound States Above Tc

H. -J. Park, C. -H. Lee, G. E. Brown +1

By extending the Bielefeld LGS (Lattice Gauge Simulation) color singlet interaction, we find that the masses of pi, sigma, rho and a_1 excitations, 32 degrees of freedom in all, go…

All-Multiplicity One-Loop Corrections to MHV Amplitudes in QCD

Darren Forde, David A. Kosower

We compute the complete one-loop corrections to the simplest class of QCD gluon amplitudes, those with two color-adjacent opposite-helicity external particles. We present results f…

Traveling waves in discretized Balitsky-Kovchegov evolution

C. Marquet, R. Peschanski, G. Soyez +1

We study the asymptotic solutions of a version of the Balitsky-Kovchegov evolution with discrete steps in rapidity. We derive a closed iterative equation in momentum space. We show…

Small-x effects in forward-jet production at HERA

Cyrille Marquet

We investigate small-x effects in forward-jet production at HERA in the two-hard-scale region kT ~ Q>>Lambda_QCD. We show that, despite describing different energy regimes, both a…
