    • Antiflow of kaons in relativistic heavy ion collisions 

      Pal, S.; Ko, Che Ming; Lin, ZW; Zhang, B. (American Physical Society, 2000)
      We compare relativistic transport model calculations to recent data on the sideward flow of neutral strange K-s(0) mesons for Au+Au collisions at 6A GeV. A soft nuclear equation of state is found to describe very well the ...
    • Baryon number fluctuation and the quark-gluon plasma 

      Lin, ZW; Ko, Che Ming. (American Physical Society, 2001)
      We show that omega (B) or omega ((B) over bar), the squared baryon or antibaryon number fluctuation per baryon or antibaryon, is a possible signature for the quark-gluon plasma that is expected to be created in relativistic ...
    • Charged particle rapidity distributions at relativistic energies 

      Lin, ZW; Pal, S.; Ko, Che Ming; Li, Ba; Zhang, B. (American Physical Society, 2001)
      Using a multiphase transport model (AMPT), which includes both initial partonic and final hadronic interactions, we study the rapidity distributions of charged particles such as protons, antiprotons, pions, and kaons in ...
    • Deuteron-nucleus collisions in a multiphase transport model 

      Lin, ZW; Ko, Che Ming. (American Physical Society, 2003)
      Using a multiphase transport model, we study pseudorapidity distributions and transverse momentum spectra in deuteron-gold collisions at RHIC. We find that final-state partonic and hadronic interactions affect the transverse ...
    • Hadronic scattering of charmed mesons 

      Lin, ZW; Ko, Che Ming; Zhang, B. (American Physical Society, 2000)
      The scattering cross sections of charm mesons with hadrons such as the pion, rho meson, and nucleon are studied in an effective Lagrangian. In heavy ion collisions, rescattering of produced charm mesons by hadrons affects ...
    • J/psi production in relativistic heavy ion collisions from a multiphase transport model 

      Zhang, B.; Ko, Che Ming; Li, Ba; Lin, ZW; Pal, S. (American Physical Society, 2002)
      Using a multiphase transport model, we study J/psi production from interactions between charm and anticharm quarks in the initial parton phase and between D and (D) over bar mesons in the final hadron phase of relativistic ...
    • J/Psi suppression in ultrarelativistic nuclear collisions 

      Zhang, B.; Ko, Che Ming; Li, Ba; Lin, ZW; Sa, BW. (American Physical Society, 2000)
      Using a multiphase transport model, we study the relative importance of J/psi suppression mechanisms due to plasma screening, gluon scattering, and hadron absorption in heavy ion collisions at the Relativistic Heavy Ion ...
    • Model for J/psi absorption in hadronic matter 

      Lin, ZW; Ko, Che Ming. (American Physical Society, 2000)
      The cross sections for J/psi absorption by pi and rho mesons are studied in a meson-exchange model that includes not only pseudoscalar-pseudoscalar-vector-meson couplings but also three-vector-meson and four-point couplings. ...
    • Multiphase transport model for relativistic heavy ion collisions 

      Lin, ZW; Ko, Che Ming; Li, Ba; Zhang, B.; Pal, S. (American Physical Society, 2005)
      We describe in detail how the different components of a multiphase transport (AMPT) model that uses the heavy ion jet interaction generator (HIJING) for generating the initial conditions, Zhang's parton cascade (ZPC) for ...
    • Partonic effects on the elliptic flow at relativistic heavy ion collisions 

      Lin, ZW; Ko, Che Ming. (American Physical Society, 2002)
      The elliptic flow in heavy ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. By converting the strings in the high energy density regions into partons, we find that the final ...
