Color evaporation and elastic [ípsilon] photoproduction at DESY HERA
(2002) [Artigo de periódico]The diffractive photoproduction of vector mesons is usually described by considering the two-gluon (Pomeron) exchange, the nondiagonal parton distributions, and the contribution of the real part to the cross section. In ... -
Dilepton low pt suppression as an evidence of the color glass condensate
(2004) [Artigo de periódico]The dilepton production is investigated in proton-nucleus collisions in the forward region using the Color Glass Condensate approach. The transverse momentum distribution (pT), more precisely the low pT region, where the ... -
Exclusive glueball production in high-energy nucleus-nucleus collisions
(2011) [Artigo de periódico]The cross sections for the glueball candidates in quasireal photon-photon collisions and on central diffraction processes (i.e., double Pomeron exchange) in heavy-ion interactions at the Relativistic Heavy-Ion Collider ... -
Exclusive photoproduction of quarkonium in proton-nucleus collisions at energies available at the CERN Large Hadron Collider
(2014) [Artigo de periódico]In this work we investigate the coherent photoproduction of ψ(1S), ψ(2S), and ϒ states in the proton-nucleus collisions in the CERN Large Hadron Collider (LHC) energies. Predictions for the rapidity distributions are ... -
Geometric scaling in inclusive charm production
(2003) [Artigo de periódico]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 saturation momentum Q2 sat x stays below ... -
Momentum space saturation model for deep inelastic scattering and single inclusive hadron production
(2011) [Artigo de periódico]We show how the Santana Amaral-Gay Ducati-Betemps-Soyez (AGBS) model, originally developed for deep inelastic scattering applied to HERA data on the proton structure function, can also describe the RHIC data on single ... -
Photon plus heavy-quark production in high-energy collisions within the target rest frame formalism
(2010) [Artigo de periódico]We apply the target rest frame formalism to photon þ heavy quark production cross section in hadronic collisions at high energies. We investigate the dependence of the production cross section on the photon and quark ...
