“…The ring imaging Cherenkov detector (RICH) [9] of the STAR-RICH collaboration is also used for particle identification. The cuts on the data for most of the TPC analyses are described in Table I, except for the upper p t cutoff, which often goes higher as shown in the graphs.…”

The results from the STAR Collaboration on directed flow (v 1 ), elliptic flow (v 2 ), and the fourth harmonic (v 4 ) in the anisotropic azimuthal distribution of particles from Au+Au collisions at √ s NN = 200 GeV are summarized and compared with results from other experiments and theoretical models. Results for identified particles are presented and fit with a blast-wave model. Different anisotropic flow analysis methods are compared and nonflow effects are extracted from the data. For v 2 , scaling with the number of constituent quarks and parton coalescence are discussed. For v 4 , scaling with v 2 2 and quark coalescence are discussed.

“…For the FTPCs the pseudorapidity acceptance is 2.4 < |η| < 4.2, only at least five hits are required, the distance of closest approach of the track to the vertex (dca) is restricted to less than 3 cm, and for the v 1 analysis the vertex z is opened up to ±50 cm. The RICH detector [9] covers |η| < 0.30 with a 20…”

“…Experiment specific event selection is described in detail in section 3.2. Figure 9 displays the pseudorapidity coverage of the suite of subsystems used to define centrality (both offline and at the trigger level) (37,38,39,40). With the exception of the STAR TPC and FTPCs, all other subsystems are intrinsically fast and available for event triggering.…”

This is a review of the theoretical background, experimental techniques, and phenomenology of what is called the "Glauber Model" in relativistic heavy ion physics. This model is used to calculate "geometric" quantities, which are typically expressed as impact parameter (b), number of participating nucleons (Npart) and number of binary nucleon-nucleon collisions (N coll ). A brief history of the original Glauber model is presented, with emphasis on its development into the purely classical, geometric picture that is used for present-day data analyses. Distinctions are made between the "optical limit" and Monte Carlo approaches, which are often used interchangably but have some essential differences in particular contexts. The methods used by the four RHIC experiments are compared and contrasted, although the end results are reassuringly similar for the various geometric observables. Finally, several important RHIC measurements are highlighted that rely on geometric quantities, estimated from Glauber calculations, to draw insight from experimental observables. The status and future of Glauber modeling in the next generation of heavy ion physics studies is briefly discussed.

“…The Relativistic Heavy-Ion Collider at Brookhaven serves four intersection points where three of the experiments, BRAHMS [15], PHENIX [14] and STAR [16] employ RICH detectors to measure, inter alia, differences in the meson/baryon and lepton/hadron production ratios in p-p vs A-A collisions. Of these only the PHENIX detector [37] is reported at this conference.…”

“…Nuclear matter is relatively transparent to leptons, so these act as a probe of the interior. Electron identification is therefore an important feature of the RICH detectors used in the AL-ICE [10], CBM [11], HRS at JLAB [12] and three of the RHIC [13] experiments-PHENIX [14], BRAHMS [15] and STAR [16]. (e) Although not contributing to this conference the physics of neutrinos, in particular the measurement of the oscillation parameters, has successfully used (in K2K [17]) and will continue to use (with T2K [18]) the upgraded SuperKamiokande [19] water Cherenkov detector.…”
