【 摘 要 】

Heavy quark production can be used as a stringent test of perturbative QCD in proton-proton collisions, and is a valuable reference for the study of heavy ion collisions. In nucleus-nucleus collisions, the measurement of heavy quark production provides a powerful tool for studying the properties of hot and dense matter created in these collisions. The PHENIX experiment has studied many important observables related to heavy flavor via leptonic measurements. Such observables include the invariant yield and azimuthal anisotropy of electrons from non-photonic sources and prompt single muons, both of which are dominated by decays of D and B mesons. Complimentary to single lepton measurements, PHENIX has measured invariant yield, flow, and polarization of various quarkonia states. Such measurements provide additional insight into heavy flavor production mechanisms. The most recent PHENIX heavy flavor results will be presented, and compared to various theoretical model predictions.
