Heavy Quark and Quarkonium Productions in High Energy Nucleus-Nucleus Collisions at RHIC and LHC(High Energy Strong Interactions 2010-Parton Distributions and Dense QCD Matter-)

PHENIX and STAR at RHIC have studied heavy quark and quarkonium productions in p+p, d+Au, Au+Au and Cu+Cu collisions. This systematic study allows to extract hot and dense medium effects on their productions after evaluating the baseline production mechanisms in p+p collisions and cold nuclear matter effects in d+Au collisions. Experimental results of heavy quark and quarkonium productions and their implications are reported in this article and future prospects for the measurements at RHIC and LHC are described.
