5 A Heavy – Flavor Tracker for STAR
We propose to construct a heavy flavor tracker for the STAR experiment at RHIC in order to measure the elliptic flow of charmed hadrons in the low pT region and identify B-meson contributions in the region pT > 4 GeV/c. In this talk, we will present the design of the detector in-depth and its expected performance as studied in detailed simulations and analytic calculations. Physics potentials o...
متن کاملOn Reconstructing Ds Mesons Using the STAR Heavy Flavor Tracker
ABSTARCT The quark-gluon matter produced in RHIC collisions has high s-quark content [1]. This suggests an equally high probability of Ds mesons formation during the different decay processes. We reconstructed Ds mesons using data from earlier runs; these encompass about ten thousand events. We also investigated the significance of the reconstructed signal as well as the efficiency of the metho...
متن کاملHeavy Flavor Production in Star
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 r...
متن کاملHeavy Flavor Production at STAR
We present measurements on D meson production via direct reconstruction of its hadronic decay channel D → Kπ in minimum bias d+Au and Au+Au collisions at √ sNN=200 GeV with pT up to ∼3 GeV/c. Non-photonic electron spectra from the charm semi-leptonic decays are analyzed from the same data set as well as in p+p collision at √ s=200 GeV using the STAR Time-of-Flight (TOF) and Barrel EMC (BEMC) de...
متن کاملAn Integrated Tracker for STAR
The STAR experiment at the Relativistic Heavy Ion Collider RHIC studies the new state of matter produced in relativistic heavy ion collisions and the spin structure of the nucleon in collisions of polarized protons. In order to improve the capabilities for heavy flavor measurements and the reconstruction of charged vector bosons an upgrade of the tracking system both in the central and the forw...
