摘要：

The study of heavy quark production extends our understanding of quark energy loss in the hot and dense matter. The measurement of non-photonic single electrons up to high p(T) provides information on charm and bottom production. The spectra from p+p, d+Au and Au+Au collisions at root s(NN) = 200 GeV have been extracted for non-photonic electrons in the range 1.5 < p(T) (GeV/c) < 10 at mid-rapidity. The corresponding nuclear modification factors (R-AA) are presented. They show a large suppression in central Au+Au collisions, indicating an unexpectedly large energy loss for heavy quarks in the hot and dense matter created at RHIC.
