摘要：

The strong suppression of hadrons with large transverse momentum (p(T)) in central Au+Au collisions observed at RHIC is generally interpreted as a consequence of energy loss of energetic partons in the hot and dense matter before fragmenting. The study of heavy quark production is testing our understanding of this scenario. The recent results on heavy flavor measurements from the STAR and PHENIX experiments at RHIC will be presented. The total charm production cross-section extracted in d + Au, Cu+Cu and Au+Au collisions at root s(NN) = 200 GeV scales with the number of binary collisions. The high pi, non-photonic electron spectra show an unexpectedly strong suppression in central Au + Au collisions. Current theoretical models do not explain this observation satisfactory. The relative contribution of charm and bottom decays to non-photonic electrons was experimentally extracted. The measurements of J/Psi and gamma production are considered as a leading probe of Quark Gluon Plasma (QGP) properties. Recent STAR and PHENIX results in quarkonia sector will be presented and discussed.
