Description

Transverse momentum (peT) distribution of electrons for 0.3 < peT < 9.0 GeV/c has been measured in midrapidity (|η| < 0.35) in Au+Au collisions and p+p collisions at √sNN = 200 GeV by the RHIC-PHENIX experiment. Two methods for background subtraction were applied to determine the electron yield from open charm and bottom decays. The nuclear modification factor was calculated, and significant suppression at high-peT was observed in Au+Au collisions, indicating the substantial energy loss of heavy quarks in a dense medium
