Abstract :
The silicon vertex tracker (VTX) was installed into the PHENIX experiment in 2010 and it successfully collected approximately 5 billion events of Au + Au collisions at 200 GeV in the 2011 RHIC run. The main function of the VTX is separation of heavy flavor hadrons, charm and bottom, with a measurement of Distance of Closest Approach (DCA) of single electrons from heavy flavor decays. By identifying electrons with PHENIX central detectors, the azimuthal anisotropy of electrons from heavy flavor decays can be determined over a broad image range.
In this paper, we will present measurement results on image and image of charged hadrons, and image of single electron from charm decay.
