“…The major subsystems at midrapidity sit inside a solenoidal magnet which provides a uniform magnetic field of 0.5 Tesla along the beam axis. Subsystems used in this analysis are the Time Projection Chamber (TPC) [21], the Time-Of-Flight (TOF) detector [22], the barrel and endcap Electromagnetic Calorimeters (EMC) [23,24], and two trigger detector subsystems: the Vertex Position Detector (VPD) [25] and the Beam Beam Counters (BBC) [26].…”

“…The timing resolution of the TOF system, including the start timing resolution in √ s = 200 GeV p + p collisions, is about 110 ps, allowing separation of K and π up to p ∼1.5 GeV/c. The barrel and endcap EMCs are designed to identify electrons and photons, covering the full azimuthal angle at |η| < 1 and 1 < η < 2, respectively [23,24]. They are fast-response detectors (< 100 ns), and were used to suppress the TPC pileup-track contribution in the event-vertex finder by matching with charged tracks from the TPC.…”

We report measurements of charmed-hadron (D 0 , D * ) production cross sections at mid-rapidity in p + p collisions at a center-of-mass energy of 200 GeV by the STAR experiment. Charmed hadrons were reconstructed via the hadronic decaysand their charge conjugates, covering the pT range of 0.6−2.0 GeV/c and 2.0−6.0 GeV/c for D 0 and D * + , respectively. From this analysis, the charm-pair production cross section at mid-rapidity is dσ/dy| cc y=0 = 170 ± 45 (stat.) +38 −59 (sys.) µb. The extracted charm-pair cross section is compared to perturbative QCD calculations. The transverse momentum dierential cross section is found to be consistent with the upper bound of a Fixed-Order Next-to-Leading Logarithm calculation.

“…The main detectors for this analysis are the Barrel Electromagnetic Calorimeter (BEMC) [5], the Barrel Shower Maximum Detector (BSMD) [5], and the Time Projection Chamber (TPC) [6]. In order to enhance the raw particle yield at high transverse momentum (p T ) an online trigger selected events with a high transverse energy deposition in a single BEMC cell.…”

“…The TPC is situated in a 0.5 Tesla solenoidal magnetic field and provides a precise measurement of the charged particle trajectories. The BEMC [ 7] is a lead-scintillator sampling calorimeter with a of depth of 21 radiation lengths (X 0 ) and an inner radius of 220 cm, divided into towers of granularity (∆η, ∆φ) = (0.05, 0.05). Two layers of gaseous shower maximum detectors (SMD), located at a depth of 5 X 0 , measure the EM shower shape with high resolution (∆η, ∆φ) = (0.007, 0.007).…”

Preliminary results on inclusive neutral pion production in d-Au collisions at √ s NN = 200 GeV in the pseudo-rapidity range 0 < η < 1 are presented. The measurement is performed using the STAR Barrel Electromagnetic Calorimeter (BEMC). In this paper, the analysis of the first BEMC hadron measurement is described and the results are compared with earlier RHIC findings. The π 0 invariant differential cross sections show good agreement with next-to-leading order (NLO) perturbative QCD calculations.
