Diffractive higgs boson photoproduction in peripheral collisions

Diffractive Higgs boson photoproduction in γp process
(2008) [Artigo de periódico]We explore an alternative process for diffractive Higgs boson production in peripheral pp collisions arising from double Pomeron exchange in photon-proton interaction. We introduce the impact factor formalism in order to ... -
Diffractive quarkonium production in association with a photon at the LHC
(2010) [Artigo de periódico]The rates for diffractive quarkonium plus prompt-photon associated production at the LHC are estimated. The theoretical framework considered in the J/Ψ (or Υ ) production associated with a direct photon at the hadron ... -
Dipole scattering amplitude in momentum space investigating fluctuations at HERA

DIS and the effects of fluctuations : a momentum space analysis
(2008) [Artigo de periódico]Among the dipole models of deep inelastic scattering at small values of the Bjorken variable x, one has been recently proposed which relates the virtual photon– proton cross section to the dipole–proton forward scattering ... -
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 ... -
Espalhamento próton-próton em altas energias e os propagadores não-perturbativos do glúon
(2023) [Dissertação]Investigamos o modelo do Pomeron como troca de dois glúons com propagadores não-perturbativos, caracterizados por uma escala de massa dinâmica. Utilizamos esse modelo de Pomeron na análise de dados de seção de choque ... -
A fenomenologia de dipolos de cor e a física de saturação em processos soft no regime de altas energias
(2019) [Dissertação]Neste trabalho investigamos as interações hadrônicas soft usando o formalismo de saturação partônica relativo a evolução não-linear da QCD (Cromodinâmica Quântica), em conjunto com a teoria de Regge, a qual e o formalismo ... -

Running coupling and pomeron loop effects on inclusive and diffractive DIS cross sections
(2012) [Artigo de periódico]Within the framework of a (1 + 1)-dimensional model which mimics high-energy QCD, we study the behavior of the cross sections for inclusive and diffractive deep inelastic γ h scattering cross sections.We analyze the cases ... -
The AGL equation from the dipole picture
(1999) [Artigo de periódico]The AGL equation includes all multiple pomeron exchanges in the double logarithmic approximation (DLA) limit, leading to a unitarized gluon distribution in the small x regime. This equation was originally obtained using ... -
The DLLA limit of BFKL in the dipole picture
(1998) [Artigo de periódico]In this work we obtain the DLLA limit of BFKL in the dipole picture and compare it with HERA data. We demonstrate that in leading – logarithmic – approximation, where a is fixed, a transition between the BFKL dynamics and ...
