[en] The HFT is a silicon detector 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 achieve about an order of magnitude better track pointing (DCA) resolution. This will allow for a direct and full topological reconstruction of charmed meson decays (e.g. D⁰) and a better determination of the B-meson spectra. Key measurements include D⁰ elliptic flow (v₂) 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 (RCP and RAA).
