Double diffractive meson production and the BFKL pomeron at e/sup +/ e/sup -/ colliders
(2006) [Artigo de periódico]In this paper we study the double diffractive vector meson production in e+ e- collisions assuming the dominance of the BFKL pomeron exchange. We consider the nonforward solution of the BFKL equation at high energy and ... -
Double vector meson production from the BFKL equation
(2005) [Artigo de periódico]The double vector meson production in two-photon collisions is addressed assuming that the color singlet t-channel exchange carries large momentum transfer. We consider the non-forward solution of the BFKL equation at high ... -
Dynamical gluon mass in QCD processes
(2007) [Artigo de periódico]We perform phenomenological applications of modified gluon propagators and running coupling constants in scattering processes in Quantum Chromodynamics (QCD). The modified forms of propagators and running coupling constant ... -
Fenomenologia em cromodinâmica quântica com propagador de glúon modificado
(2003) [Tese]A aplicabilidade e usos de propagadores de glúon modificados na Cromodinâmica Quântica (QCD) em diferentes espécies de processos é analisada. Os propagadores modificados de glúon são obtidos por diversos métodos, em especial, ... -
Meson form factors and nonperturbative gluon propagators
(2003) [Artigo de periódico]The meson (pion and kaon) form factor is calculated in the perturbative framework with alternative forms for the running coupling constant and the gluon propagator in the infrared kinematic region. These modified forms are ... -
Non-perturbative gluons in diffractive photo-production of J/[psi]
(2001) [Artigo de periódico]The modifications induced in the calculation of the cross section of the diffractive process γγ →J/ [psi] J/ [psi], when the gluon propagator is changed are analyzed. Instead of the usual perturbative gluon propagator, ... -
Parton saturation scaling function for exclusive production of vector mesons and deeply virtual Compton scattering
(2017) [Artigo de periódico]We provide a universal expression of cross sections for the exclusive vector meson production and deeply virtual Compton scattering (DVCS) in photon-proton and photon-nucleus interactions based on the geometric scaling ... -

The QCD pomeron in ultraperipheral heavy ion collisions : V. double vector meson production in the BFKL approach
(2006) [Artigo de periódico]In this work the double vector meson production in ultraperipheral heavy ion collisions is investigated within the BFKL approach. The integrated cross sections and event rates for the processes AA→V1V2 AA (Vi = ρ, ω, φ, ...
