“…Showers from neutral hadrons and especially anti-neutrons can be misidentified as photons. To correct for this contamination of the inclusive photon yield a GEANT simulation of the detector was used which had the proton and anti-proton spectra as an input [10]. The data have been corrected for reconstruction and trigger efficiencies, limited acceptance, photon conversions in the detector material in front of the BEMC, and the inefficiency of the CPV.…”

“…The precision in the first results on the NMFs R AA , were limited by the uncertainty in the parameterization of the p+p reference spectrum used in obtaining R AA . This limitation was partly overcome when new data on p+p, d+Au and Au+Au collisions at √ s N N =200 GeV using the same experimental setup were obtained [61,62,63,64,65,66,67,68,69,70,71,72].…”

The effect of fluctuations of strong color electric fields (SCF) on the baryon production in d+Au and Au+Au collisions at 200A GeV is studied in the framework of the HIJING/BB v2.0 model. It is shown that the dynamics of the production process deviates considerably from calculations based on Schwinger-like estimates for homogeneous and constant color fields. An increase of the string tension from κ0 = 1 GeV/fm, to in medium mean values of 1.5 to 2.0 GeV/fm and 2.0 to 3.0 GeV/fm for d+Au and Au+Au, respectively, results in a consistent description of the observed nuclear modification factors R dAu and RAuAu (that relates (d)Au+Au and p+p collisions), and point to the relevance of fluctuations of transient color fields. The differences between nuclear modification factors RAuAu and RCP (that relates central and peripheral collisions) are also discussed. The measurement of multi-strange (anti)hyperons (Ξ, Ω) yields would provide a crucial test of the importance of SCF fluctuations at RHIC energies.

“…By measuring R AA ,p/p andp/π ratios, we will be able to access the difference between gluon and quark energy loss. This was done by STAR Collaboration in a recent publication [31] using the relativistic rise of ionization energy loss in TPC to separate protons and pions [34]. The results show that there is no difference between proton and pion R AA (or R CP ) and little centrality dependence ofp/π ratio has been found [31].…”

Abstract. In this presentation, I discussed a) the charm total cross-section and its comparisons to measurements at other beam energies and pQCD calculations; b) the semileptonic decay of charmed hadrons and the sensitivity of non-photonic leptons to charm quark collective flow and freeze-out; c) semileptonic decayed electron spectrum at high transverse momentum, its comparison to FONLL in p+p and d+Au collisions, and heavy-quark energy loss in Au+Au collisions.In relativistic heavy-ion collisions, charm quarks are believed to be produced in the early stage via initial gluon fusion and their production cross-section can be evaluated using perturbative QCD [1]. Study of the N bin scaling properties of the charm total cross-section in p+p, d+Au and Au+Au collisions can test if heavy-flavor quarks, which are used as a probe, are produced exclusively at the initial impact. The interactions of heavy quarks with the medium provide a unique tool for probing the hot and dense matter created in ultra-relativistic heavy-ion collisions at the early times. At RHIC energies, heavy quark energy loss [2], charm quark coalescence [3,4,5,6], the effect of J/ψ production from charm quark coalescence on the interpretation of possible J/ψ suppression due to color screening [7], and charm flow [8,9,10] have been proposed as important tools in studying the properties of matter created in heavy ion collisions. The last three effects depend strongly on the charm total cross-section and spectrum at low p T .Since the beginning of RHIC operation, PHENIX and STAR collaborations have made pioneer measurements in charm related physics [11,12,13,14,15,16] ‡. New measurements presented at this conference are: (i) muon spectra at forward rapidity (1.4 < |y| < 2.2) from charm semileptonic decay by PHENIX Collaboration [16]. This enables us to study the rapidity dependence of nuclear effects of charm production.(ii) muon spectra at low p T (0.17 < p T < 0.25 GeV/c) from charm semileptonic decay by STAR Collaboration [15]. This improves the charm total cross-section measurements and better constrains the charm spectrum for studying the charm radial flow. ‡ The overviews of charm elliptic flow and quarkonium can be found elsewhere [17,18]
