Charm and Charmonium in the Quark-gluon Plasma
In the first part of the talk, we briefly review the problem of parton-energy loss and thermalization at the Relativistic Heavy-Ion Collider and discuss how heavy quarks (charm and bottom) can help to resolve the existing experimental and theoretical puzzles. The second part of the talk is devoted to the properties of heavy quarkonia in the (strongly interacting) Quark-Gluon Plasma (sQGP) and t...

متن کاملCharmonium in a weakly coupled quark-gluon plasma.
We present a model of charmonium as two heavy quarks propagating classically in a weakly coupled quark-gluon plasma. The quarks interact via a static, color-dependent potential and also suffer collisions with the plasma particles. We calculate the radiation width of the color octet state (for fixed, classical qq̄ separation) and find that it is long-lived provided a finite gluon mass is used to ...
متن کاملTowards the Quark-Gluon Plasma
We discuss recent experimental results in the field of ultra-relativistic nuclear collisions. The emerging “picture” is a collectively expanding, initially hot and dense fireball in which strangenessand low-mass di-lepton pair production are enhanced and J/Ψ production is suppressed compared to expectations from nucleon-nucleon collisions. It is argued that, taken together, these data provide c...
متن کاملsignal the quark gluon plasma ?
We first review the production and the possible chemical equilibration of strange particles at CERN-SPS energies within a microscopic hadronic transport calculation. It is shown in particular that the strange quarks are produced initially via string excitations in the primary, secondary and ternary interactions. We then further elaborate on a recent idea of antihyperon production by multi-meson...
