【 摘 要 】

Heavy quarkonia are direct probes of deconfinement in the quark gluon plasma formed in heavy ion collisions. Other effects also occur, such as modification of the parton distributions in cold nuclear matter, and a multidimensional description is necessary to disentangle the various contributions. Characterization of the production processes in p+p and p or d induced collisions with ions is critical in the extraction of the additional effects in ionion collisions. The Relativistic Heavy Ion Collider has delivered a wide range of systems and energies, from p+p to Au+Au through d+Au and Cu+Au, from 7.6 to 200 GeV (N-N collision energy), allowing the PHENIX experiment to start exploring these experimentally available dimensions for open and hidden charm and beauty as a function of rapidity and transverse momentum. Recent PHENIX results on heavy flavor production measured through lepton pairs or singles, including J/Ψ, Ψ', Χc, Υ and open charm and beauty, are presented.
