$J/\psi$ enhancement in heavy ion collisions: Statistical and kinetic approach

Content:

At Large Hadron Collider (LHC), collisions of Pb+Pb ions at energies $\sqrt s_{NN}$ = 2.76 TeV would create strongly interacting matter at very high temperatures, where a phase transition from hadronic phase to quark gluon plasma (QGP) is expected. The J/$\psi$ particles are the richest and most interesting probes of QGP. The SPS data convincingly show that J/$\psi$ is suppressed, while PHENIX data are explained by accounting for both partial suppression and partial enhancement scenarios. At LHC, a large number of $c \bar c$ pairs are produced initially which could lead to an important source of final charmonium. This coalescence mechanism may lead to enhancement instead of suppression of J/$\psi$ at LHC. We discuss the charmonium (J/$\psi$) enhancement in the nucleus-nucleus collsions within the framework of statistical hadronization and the kinetic formation approach. We compare our results with the J/$\psi$ measured at SPS and RHIC. Also we predict the number of J/$\psi$ which will be measured in the first year of heavy ion run at LHC in Pb+Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV.
