Research Plan at RIKEN CC-J Date: 14/ 4/2006 (DD/MM/YY) To: the Planning and Coordination Office of RIKEN CC-J Reseach Subject :RUN4 Au+Au electron-hadron correlation (PHENIX official or not : no ) Person responsible for this research: Name :Yuhei Morino Tel/Fax :048-464-4582 E-mail :y.morino@cns.s.u-tokyo.ac.jp Person responsible for the job submission: Name :Yuhei Morino Tel/Fax :048-464-4582 E-mail :y.morino@cns.s.u-tokyo.ac.jp Summary of this research (10-100 lines) This research is aimed for the study of the energy loss mechanism of heavy quark in the hot and dense medium. Since the main source of high-pt electrons is the semi-leptonic decay of D or B meson, low pt charged particles associated high pt electron may have the information of the heavy quark's energy loss in the hot and dense medium. This research needs pico DST data set which contain the information of triggered high pt electron and associated charged particle.
