J/ production in relativistic heavy ion collisions from a multiphase transport model Academic Article

abstract

• Using a multiphase transport model, we study J/ production from interactions between charm and anti-charm quarks in the initial parton phase and between D and D mesons in the final hadron phase of relativistic heavy ion collisions at the relativistic heavy ion collider. Including also the inverse reactions of J/ absorption by gluons and light mesons, we find that the net number of J/ from the parton and hadron phases is smaller than that expected from the superposition of initial nucleon-nucleon collisions, contrary to the J/ enhancement predicted by the kinetic formation model. The production of J/ is further suppressed if one includes the color screening effect in the parton phase. We have also studied the dependence of J/ production on the charm quark mass and the effective charm meson mass.
