00 1 1 On Charm Production near the Phase Boundary
نویسندگان
چکیده
We discuss aspects of the statistical hadronization model for the production of mesons with open and hidden charm in ultra-relativistic nuclear collisions. Emphasis is placed on what can be inferred from the dependence of the yield of charmonia on the number of participants in the collisions.

We present recent results on charm physics from CLEO-III, emphasizing QCD and hadronic structure. These include the decay Ξ 0 c → pK − K − π + and the form factor for D 0 → π − e + νe. We also discuss upcoming measurements with CLEO-c, including dramatic improvements in the D 0 → π − e + νe form factor, and glueball spectroscopy in J/ψ → γX. The CLEO collaboration has been in existence for over...

Some recent ZEUS results on the photoproduction of open charm and possible implications for photon structure are discussed. 1 Open Charm Photoproduction at HERA Photoproduction of ‘open’ charm (as opposed to cc̄ bound states) can take place via several processes at HERA. The most obvious is photon-gluon fusion. The photon interacts directly with a gluon from the proton via t-channel charm quark,...
متن کاملEvidence for charmonium generation at the phase boundary in ultra-relativistic nuclear collisions
We investigate the transition from suppression to enhancement of J/ψ mesons produced in ultra-relativistic nuclear collisions in the framework of the statistical hadronization model. The calculations are confronted with the most recent data from the RHIC accelerator. This comparison yields first direct evidence for generation of J/ψ mesons at the phase boundary. Based on the success of this app...
