Parton saturation approach in heavy quark production at high energies

VP Goncalves, MVT Machado - Modern Physics Letters A, 2004 - World Scientific
The high parton density regime of the quantum chromodynamics (QCD), where the physics
of parton saturation is expected to be dominant, is briefly discussed. Some …

On solutions of the Balitsky–Kovchegov equation with impact parameter

K Golec-Biernat, AM Staśto - Nuclear Physics B, 2003 - Elsevier
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 …

[HTML][HTML] Geometric scaling in diffractive deep inelastic scattering

C Marquet, L Schoeffel - Physics Letters B, 2006 - Elsevier
The geometric scaling property observed in the HERA data at small x, that the deep inelastic
scattering (DIS) total cross-section is a function of only the variable Q2xλ, has been argued …

A linear evolution for non-linear dynamics and correlations in realistic nuclei

E Levin, M Lublinsky - Nuclear Physics A, 2004 - Elsevier
A new approach to high energy evolution based on a linear equation for QCD generating
functional is developed. This approach opens a possibility for systematic study of …

Saturation effects in exclusive ρ T, L meson electroproduction

A Besse, L Szymanowski, S Wallon - Journal of High Energy Physics, 2013 - Springer
A bstract We use recent results for the\(\gamma_L^{*}\to {\rho_L}\) and\(\gamma_T^{*}\to
{\rho_T}\) impact factors, computed in the impact parameter representation within the …

Geometric scaling in inclusive charm production

VP Goncalves, MVT Machado - Physical review letters, 2003 - APS
We show that the cross section for inclusive charm production exhibits geometric scaling in a
large range of photon virtualities. In the DESY ep collider HERA kinematic domain the …

Traveling waves and geometric scaling at nonzero momentum transfer

C Marquet, R Peschanski, G Soyez - Nuclear Physics A, 2005 - Elsevier
We extend the search for traveling-wave asymptotic solutions of the nonlinear Balitsky–
Kovchegov (BK) saturation equation to non-forward dipole–target amplitudes. Making use of …

Heavy quark photoproduction in proton-proton collisions

VP Goncalves, MVT Machado - … Review D—Particles, Fields, Gravitation, and …, 2005 - APS
We calculate the photoproduction of heavy quarks in proton-proton collisions at RHIC,
Tevatron, and CERN LHC energies, where the photon reaches energies larger than those …

Correlation of small-x gluons in impact parameter space

Y Hatta, AH Mueller - Nuclear Physics A, 2007 - Elsevier
In the framework of the QCD dipole model at high energy, we present an analytic evaluation
of the dipole pair density in two limits in which the parent dipole is much larger/smaller than …

The dipole representation of vector meson electroproduction beyond leading twist

A Besse, L Szymanowski, S Wallon - Nuclear Physics B, 2013 - Elsevier
We link the recent computation beyond leading twist of the impact factor of the transition
γT⁎→ ρT performed in the light-cone collinear approach, to the dipole picture by expressing …
