  • Ducati, Maria Beatriz de Leone Gay; Gonçalves, Victor Paulo Barros; Mackedanz, Luiz Fernando (2003)
    At high energies the saturation effects associated to the high parton density should modify the behavior of the observables in proton-nucleus and nucleus-nucleus scattering. In this paper we investigate the saturation ...
  • Ducati, Maria Beatriz de Leone Gay; Gonçalves, Victor Paulo Barros; Mariotto, Cristiano Brenner (2002)
    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 ...
  • Ducati, Maria Beatriz de Leone Gay; Mackedanz, Luiz Fernando; Gonçalves, Victor Paulo Barros (2004)
    The D meson production at forward rapidities in d+Au processes is calculated using a pQCD based model, assuming that this treatment could be used as a baseline for distinct dynamical and medium effects. It is analysed ...
  • Ducati, Maria Beatriz de Leone Gay; Gonçalves, Victor Paulo Barros; Mackedanz, Luiz Fernando (2007)
    The discovery of the jet quenching in central Au + Au collisions at the Relativistic Heavy-ion Collider (RHIC) has provided clear evidence for the formation of strongly interacting dense matter. It has been predicted to ...
  • Mariotto, Cristiano Brenner; Gonçalves, Victor Paulo Barros (2007)
    In this Brief Report we estimate the influence of nonlinear gluon evolution in the production of prompt photons at the Large Hadron Collider (LHC) pp collider. We assume the validity of collinear factorization and consider ...
  • Ayala Filho, Alvaro Leonardi; Mariotto, Cristiano Brenner; Gonçalves, Victor Paulo Barros (2007)
    In this paper we estimate the influence of the shadowing effect and initial state parton energy loss in the quarkonium production at HERA-B. We analyze the xF behavior of the effective exponent α(xF) and present a comparison ...
  • Mariotto, Cristiano Brenner; Gonçalves, Victor Paulo Barros (2008)
    The production of prompt photons at high energies provides a direct probe of the dynamics of strong interactions. In particular, one expects that it could be used to constrain the behavior of the nuclear gluon distribution ...
  • Ducati, Maria Beatriz de Leone Gay; Gonçalves, Victor Paulo Barros; Mackedanz, Luiz Fernando (2007)
    The discovery of the jet quenching in central Au + Au collisions at the Relativistic Heavyion Collider (RHIC) at Brookhaven National Laboratory has provided clear evidence for the formation of strongly interacting dense ...
