Ω and φ in Au+Au collisions at sqrt(SNN)=200 and 11.5 GeV from a multiphase transport model

  • Within the framework of a multiphase transport model, we study the production and properties of Ω and φ in Au + Au collisions with a new set of parameters for √sNN=200 GeV and with the original set of parameters for √sNN=11.5 GeV. The AMPT model with string melting provides a reasonable description at √sNN=200 GeV, while the default AMPT model describes the data well at √sNN=11.5 GeV. This indicates that the system created at top RHIC energy is dominated by partonic interactions, while hadronic interactions become important at lower beam energy, such as √sNN=11.5 GeV. The comparison of N+-)/[2N(φ)] ratio between data and calculations further supports the argument. Our calculations can generally describe the data of nuclear modification factor as well as elliptic flow.

Abstract: Within the framework of a multiphase transport model, we study the production and properties of Ω and φ in Au + Au collisions with a new set of parameters for √sNN=200 GeV and with the original set of parameters for √sNN=11.5 GeV. The AMPT model with string melting provides a reasonable description at √sNN=200 GeV, while the default AMPT model describes the data well at √sNN=11.5 GeV. This indicates that the system created at top RHIC energy is dominated by partonic interactions, while hadronic interactions become important at lower beam energy, such as √sNN=11.5 GeV. The comparison of N+-)/[2N(φ)] ratio between data and calculations further supports the argument. Our calculations can generally describe the data of nuclear modification factor as well as elliptic flow.
