Heavy Flavor Production in STAR

Abstract

In this contribution, the STAR collaboration at RHIC reports on measurements related to heavy flavor production. We present results from D meson production, and from indirect reconstruction of heavy flavor via semi-leptonic decays, including low transverse momentum muons and the inclusive yield of non-photonic electrons. We focus on the non-photonic electrons, and present results over a broad range of transverse momenta (1.2 < pT < 10 Gev-c) in p+p, d+Au, and Au+Au collisions at sqrt(s) = 200 GeV. The non-photonic electron yield exhibits unexpectedly large suppression in central Au+Au collisions at high pT, suggesting substantial heavy quark energy loss in hot QCD matter.
