【 摘 要 】

Heavy quarks are important probes to understand the properties of the Quark Gluon Plasma (QGP) created in the relativistic heavy-ion collision. The PHENIX measurement of electrons from heavy-flavor decays shows large flow and strong suppression in Au+Au collisions at 200 GeV [1][2], which is not well understood. In these proceedings, we will present both the new PHENIX heavy-flavor electron v2results in Au+Au collisions at 62.4 GeV collisions using the Hadron Blind Detector (HBD) and the latest PHENIX measurement of charm and bottom separately in p+p collisions at 200 GeV with the recently installed Silicon Vertex Track (VTX).
