Charm and bottom production in inclusive double Pomeron exchange in heavy-ion collisions at energies available at the CERN Large Hadron Collider
Gay Ducati, Maria Beatriz; Machado, Mairon Melo; Machado, Magno Valério Trindade (2011) [Artigo de periódico]The inclusive double Pomeron exchange cross section for heavy-quark pair production is calculated for nucleus-nucleus collisions at the Large Hadron Collider. The present estimate is based on hard diffractive factorization, ... -
Diffractive hadroproduction of W/sup +-/ and Z /sub 0/ bosons at high energies
Gay Ducati, Maria Beatriz; Machado, Mairon Melo; Machado, Magno Valério Trindade (2007) [Artigo de periódico]Results from a phenomenological analysis of W and Z hard diffractive hadroproduction at high energies are reported. Using the Regge factorization approach, we consider the recent diffractive parton density functions extracted ... -
Diffractive quarkonium production in association with a photon at the LHC
Gay Ducati, Maria Beatriz; Machado, Mairon Melo; Machado, Magno Valério Trindade (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 ... -
Estimate of the single diffractive heavy quark production in heavy ion collisions at the CERN LHC
Gay Ducati, Maria Beatriz; Machado, Mairon Melo; Machado, Magno Valério Trindade (2010) [Artigo de periódico]The single diffractive cross section for heavy quarks production is calculated at next-to-leading order (for nucleus-nucleus collisions. Such processes are expected to occur at the LHC, where the nuclei involved are lead ... -
Estimations for the single diffractive production of the Higgs boson at the Tevatron and the LHC
Gay Ducati, Maria Beatriz; Machado, Mairon Melo; Silveira, Gustavo Gil da (2011) [Artigo de periódico]The single diffractive production of the standard model Higgs boson is computed using the diffractive factorization formalism, taking into account a parametrization for the Pomeron structure function provided by the H1 ... -
Neutral current neutrino-nucleus interactions at high energies
Gay Ducati, Maria Beatriz; Machado, Mairon Melo; Machado, Magno Valério Trindade (2009) [Artigo de periódico]We present a QCD analysis of the neutral current (NC) neutrino-nucleus interaction at the small-x region using the color dipole formalism. This phenomenological approach is quite successful in describing experimental results ... -
Neutrino structure functions in the QCD dipole picture
Gay Ducati, Maria Beatriz; Machado, Mairon Melo; Machado, Magno Valério Trindade (2007) [Artigo de periódico]In this contribution we present an exploratory QCD analysis of the neutrino structure functions in charged current DIS using the color dipole formalism. The corresponding dipole cross sections are taken from recent ... -
Small-x neutrino-hadron structure functions within the QCD color dipole picture
Gay Ducati, Maria Beatriz; Machado, Mairon Melo; Machado, Magno Valério Trindade (2007) [Artigo de periódico]We present an exploratory QCD analysis of the neutrino structure functions in charged current DIS using the color dipole formalism. The dipole cross sections are taken from recent phenomenological/theoretical studies in ...
