Charmonium production from hot hadronic matter Academic Article uri icon

abstract

  • Charmonium production from DD annihilation in the hadron gas formed in ultra-relativistic heavy-ion collisions is studied. With initial conditions taken from the HIJING parton model, we have estimated the number of J/ produced from an expanding hadron gas, using the J/ absorption and production cross sections obtained from either an effective Lagrangian or the quark-exchange model. We find that J/ production is negligible in heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC) but may be important at the Large Hadron Collider (LHC), where more charm mesons are produced. Similar results are obtained for ' production from the hadron gas at RHIC and LHC. 1998 Elsevier Science B.V. All rights reserved.
