摘要：

The HFT is the vertex-detector upgrade for the STAR experiment at RHIC. It is replacing the decommissioned silicon drift, detector (SVT) with active pixel technology close to the beam pipe in order to increase by about an order of magnitude the track-pointing (DCA) resolution. This will allow direct and full topological reconstruction of charmed meson decays (e.g. D-0) and a better determination of the B-meson spectra. Key measurements include D-0 elliptic flow (v(2)) determination, especially in the lower transverse momenta (p(T)) region, and identified heavy quark suppression studies at high p(T) via the nuclear modification factor (R-CP and R-AA).
