    In This communication, we report results of three-dimensional hydrodynamic computations, by using equations of state with a critical end point as suggested by the lattice QCD. Some of the results are an increase of the ...
  • Aguiar, Carlos Eduardo; Andrade, Rone Peterson Galvão de; Grassi, Frederique Marie-Brigitte Sylvie; Hama, Yogiro; Socolowski Junior, Otavio (2004)
    Using the hydrodynamical code NeXSPheRIO, we compare predictions as usually done in hydrodynamics, using centrality windows defined through the impact parameter, and as obtainable experimentally, using windows in participant ...
  • Andrade, Rone Peterson Galvão de; Grassi, Frederico; Hama, Yogiro; Kodama, Takashi; Socolowski Junior, Otavio (2007)
    Elliptic flow at RHIC is computed event-by-event with NeXSPheRIO. We show that when symmetry of the particle distribution in relation to the reaction plane is assumed, there is a disagreement between the true and reconstructed ...
  • Hama, Yogiro; Grassi, Frederico; Socolowski Junior, Otavio (2005)
    We study effects of the event-by-event fluctuation of the initial conditions and the continuous pion emission during the whole development of the hot and dense matter formed in high-energy collisions on the two-pion ...
  • Gazdzicki, Marek; Gorenstein, Mark; Grassi, Frederico; Hama, Yogiro; Kodama, Takashi; Socolowski Junior, Otavio (2004)
    We study, in a hydrodynamical approach, the energy dependence of the kaon mT spectra in central Pb+Pb (Au+Au) collisions. We show that the experimental data of the inverse slope parameter can be reproduced with a reasonable ...
  • Grassi, Frederique Marie-Brigitte Sylvie; Hama, Yogiro; Kodama, Takeshi; Socolowski Junior, Otavio (2004)
    We show that a hydrodynamical model with continuous particle emission instead of sudden freeze out may explain both the observed strange particle and pion abundances and transverse mass spectra for light projectile at SPS ...
  • Quian, Wei Liang; Andrade, Rone Peterson Galvão de; Socolowski Junior, Otavio; Grassi, Frederico; Kodama, Takashi; Hama, Yogiro (2007)
    The transverse momentum distributions of hadrons in 200GeV Au-Au collisions at RHIC are calculated using the smoothed particle hydrodynamics code SPheRIO. They are compared with data from STAR and PHOBOS Collaborations. ...
  • Andrade, Rone Peterson Galvão de; Hama, Yogiro; Grassi, Frederico; Socolowski Junior, Otavio; Kodama, Takashi (2007)
    Elliptic flow at RHIC is computed event by event with NeXSPheRIO. Reasonable agreement with experimental data on v2(h) and v2(pt) is obtained. Various effects are studied as well: equation of state (with or without critical ...
  • Hama, Yogiro; Kodama, Takashi; Socolowski Junior, Otavio (2005)
    A survey is given on the applications of hydrodynamic model of nucleus-nucleus collisons, focusing especially on i) the resolution of hydrodynamic equations for arbitrary configurations, by using the smoothed-particle ...
