1 Statistical Coalescence Model with Exact Charm Conservation
The statistical coalescence model for the production of open and hidden charm is considered within the canonical ensemble formulation. The data for the J/ψ multiplicity in Pb+Pb collisions at 158 A·GeV are used for the model prediction of the open charm yield which has not yet been measured in these reactions. The charmonium states J/ψ and ψ have been measured in nucleus-nucleus (A+A) collision...

متن کاملQuark Coalescence and Charm(onium) in QGP
The potential of heavy quarks as probes of the environment produced in hadronic and heavy-ion reactions is discussed. A key role is played by coalescence processes and/or resonance formation which are promising candidates to provide a comprehensive understanding of phenomena associated with reinteractions of both open and hidden heavy-quark states.

متن کاملCharm elliptic flow from quark coalescence dynamics
From covariant transport theory, a significant ∼ 10% light quark elliptic flow at RHIC implies an elliptic flow of similar magnitude for charm quarks, at moderately large pT > 2.5 − 3 GeV. At lower transverse momenta, charm quark elliptic flow reduces progressively, reminiscent of the mass ordering pattern in ideal hydrodynamics. From the quark flows we predict the elliptic flow of D mesons at ...

We consider the production of the J/ψ mesons in heavy ion collisions at RHIC energies in the statistical coalescence model with an exact (canonical ensemble) charm conservation. The cc quark pairs are assumed to be created in the primary hard parton collisions, but the formation of the open and hidden charm particles takes place at the hadronization stage and follows the prescription of statist...
