In-medium effects on charmonium production in heavy-ion collisions.
Charmonium production in heavy-ion collisions is investigated within a kinetic theory framework incorporating in-medium properties of open- and hidden-charm states in line with recent QCD lattice calculations. A continuously decreasing open-charm threshold across the phase boundary of hadronic and quark-gluon matter is found to have important implications for the equilibrium abundance of charmo...
متن کاملExcitation function Analysis for Charmonium Production in Heavy-Ion Collisions
Both color screening and regeneration are hot medium effects on charmonium production in heavy ion collisions. While they affect in an opposite way the charmonium yield, their competition in transverse dynamics bring sensitivity to the ratio of averaged transverse momentum square for charmonium, which thus can reveal more nature of the QCD medium created from the collisions. We make an excitati...
متن کاملSecondary Charmonium Production in Heavy Ion Collisions at LHC Energy
We consider the production of charmonium by DD̄ annihilation during the mixed and hadronic phase of a Pb-Pb collision at LHC energy. The calculations for secondary J/ψ and ψ production are performed within a kinetic model taking into account the spacetime evolution of a longitudinally and transversely expanding medium. It is shown that the yield of secondary J/ψ mesons depends strongly on the J/...
متن کاملCharmonium and bottomonium production in heavy-ion collisions
We review the present status in the theoretical and phenomenological understanding of charmonium and bottomonium production in heavy-ion collisions. Starting from an introductory historical perspective, recapitulating the basic notion of “anomalous quarkonium suppression” in heavy-ion collisions, we develop ingredients and concepts aimed at a comprehensive approach to utilize heavy quarkonia as...
متن کاملChiral kaon dynamics in heavy ion collisions
The influence of the chiral mean field on the collective motion of kaons in relativistic heavy ion reactions at SIS energies is investigated. We consider three types of collective motion, i.e. the transverse flow, the out-of-plane flow (squeeze-out) and the radial flow. The kaon dynamics is thereby described with a relativistic mean field as it originates form chiral lagrangiens. For the K meso...
