Abstract: Recent Charm Measurements Through Hadronic Decay Channels in 200 GeV Heavy Ion Collisions at the
STAR Experiment at RHIC
The STAR experiment has been measuring the yields of charm mesons by reconstruction from their hadronic
decay channels. Recently, the charm cross-section in 200 GeV Cu+Cu collisions has been obtained from the
measured D0 spectra. We present this result and compare it to previous experimental results and to
pQCD predictions. pQCD predicts that most charm is produced during initial gluon fusion and therefore the
cross-section should scale with the number of binary collisions. We also report on the progress of
extracting the Ds (charm-strange) yield by using the Silicon Vertex Tracker (SVT) to identify the secondary
vertices of charm decays.\
