Description
PHENIX has measured single electrons from charm and bottom decays at
midrapidity in Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV.
Previous heavy-flavor electron measurements have indicated
substantial modification of the momentum distribution of the parent
heavy-flavor hadrons. Using the PHENIX barrel silicon-vertex tracker
(VTX) to measure displaced vertices precisely, the relative
contributions from charm and bottom hadrons to these electrons have
been measured as a function of transverse momentum in Au$+$Au
collisions at $\sqrt{s_{NN}}$=200 GeV. The heavier bottom quarks
significantly extend our probes of the quark-gluon plasma, and the
results are compared with theoretical calculations.
