Heavy-Flavor: First J/ results

• Motivation: Suppression of heavy quarkonia states due to screening of color potential at deconfinement.

• J/  e+e- (mid-rapidity) in AuAu:

• N=10.8  3.2 (stat)  3.8 (sys)

• Centrality dependence of J/ yield:

• Strong J/ψ enhancement ruled out. No definite conclusion on suppression yet.

• Higher luminosity running needed.
