    The use of PHENIX experiment at midrapidity in Au + Au collision at √sNN = 200 GeV for calculating Bose-Einstein correlation of identical charged ion pairs was discussed. It was found that the Bertsch-Partt radius parameters were determined as a function of the transverse momentum of the pair and as function of the collision. It was also observed that the value of Rout/Rside, as function of kT decrease from ∼1.1 to ∼ 0.8 over the range of kT. The results show that the measurements of the transverse momentum dependence of the HBT radii.

    Inclusive transverse momentum spectra of η mesons have been measured within pT=2-10GeV/c at midrapidity by the PHENIX experiment in Au+Au collisions at sNN=200GeV. In central Au+Au the η yields are significantly suppressed compared to peripheral Au+Au, d+Au, and p+p yields scaled by the corresponding number of nucleon-nucleon collisions. The magnitude, centrality, and pT dependence of the suppression is common, within errors, for η and π0. The ratio of η to π0 spectra at high pT amounts to 0.40

    Measurements of neutral pion (π0) production at midrapidity in sNN=200 GeV Au+Au collisions as a function of transverse momentum, pT, collision centrality, and angle with respect to reaction plane are presented. The data represent the final π0 results from the PHENIX experiment for the first RHIC Au+Au run at design center-of-mass energy. They include additional data obtained using the PHENIX Level-2 trigger with more than a factor of 3 increase in statistics over previously published results for pT>6 GeV/c. We evaluate the suppression in the yield of high-pT π0's relative to pointlike scaling expectations using the nuclear modification factor RAA. We present the pT dependence of RAA for nine bins in collision centrality. We separately integrate RAA over larger pT bins to show more precisely the centrality dependence of the high-pT suppression. We then evaluate the dependence of the high-pT suppression on the emission angle Δ of the pions with respect to event reaction plane for seven bins in collision centrality. We show that the yields of high-pT π0's vary strongly with Δ, consistent with prior measurements. We show that this variation persists in the most peripheral bin accessible in this analysis. For the peripheral bins we observe no suppression for neutral pions produced aligned with the reaction plane, whereas the yield of π0's produced perpendicular to the reaction plane is suppressed by a factor of ~2. We analyze the combined centrality and Δ dependence of the π0 suppression in different pT bins using different possible descriptions of parton energy loss dependence on jet path-length averages to determine whether a single geometric picture can explain the observed suppression pattern. © 2007 The American Physical Society.

    The anisotropy parameter ([Formula presented]), the second harmonic of the azimuthal particle distribution, has been measured with the PHENIX detector in [Formula presented] collisions at [Formula presented] for identified and inclusive charged particle production at central rapidities ([Formula presented]) with respect to the reaction plane defined at high rapidities ([Formula presented]). We observe that the [Formula presented] of mesons falls below that of (anti)baryons for [Formula presented], in marked contrast to the predictions of a hydrodynamical model.

    Emission source functions are extracted from correlation functions constructed from charged pions produced at midrapidity in Au+Au collisions at sNN=200GeV. The source parameters extracted from these functions at low kT give first indications of a long tail for the pion emission source. The source extension cannot be explained solely by simple kinematic considerations. The possible role of a halo of secondary pions from resonance emissions is explored. © 2007 The American Physical Society.

    Extensive experimental data from high-energy nucleus-nucleus collisions were recorded using the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). The comprehensive set of measurements from the first three years of RHIC operation includes charged particle multiplicities, transverse energy, yield ratios and spectra of identified hadrons in a wide range of transverse momenta (pT), elliptic flow, two-particle correlations, nonstatistical fluctuations, and suppression of particle production at high pT. The results are examined with an emphasis on implications for the formation of a new state of dense matter. We find that the state of matter created at RHIC cannot be described in terms of ordinary color neutral hadrons. © 2005 Elsevier B.V. All rights reserved.

    Inclusive transverse momentum spectra of η mesons in the range pTf2-12 GeV/c have been measured at midrapidity (|η|<0.35) by the PHENIX experiment at RHIC in p+p,d+Au, and Au+Au collisions at sNN=200 GeV. The η mesons are reconstructed through their η→γγ channel for the three colliding systems as well as through the η→π0π+π- decay mode in p+p and d+Au collisions. The nuclear modification factor in d+Au collisions, RdAu(pT)1.0-1.1, suggests at most only modest pT broadening ("Cronin enhancement"). In central Au+Au reactions, the η yields are significantly suppressed, with RAuAu(pT)0.2. The ratio of η to π0 yields is approximately constant as a function of pT for the three colliding systems in agreement with the high-pT world average of Rη/π00.5 in hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions for a wide range of center-of-mass energies (sNN3-1800 GeV) as well as, for high scaled momentum xp, in e+e- annihilations at s=91.2 GeV. These results are consistent with a scenario where high-pT η production in nuclear collisions at the Relativistic Heavy Ion Collider is largely unaffected by initial-state effects but where light-quark mesons (π0,η) are equally suppressed due to final-state interactions of the parent partons in the dense medium produced in Au+Au reactions. © 2007 The American Physical Society.

    The centrality dependence of transverse momentum distributions and yields for π±,K±, p, and p in Au +Au collisions at √sNN=200 GeV at midrapidity are measured by the PHENIX experiment at the Relativistic Heavy Ion Collider. We observe a clear particle mass dependence of the shapes of transverse momentum spectra in central collisions below ∼2 GeV/c in pT. Both mean transverse momenta and particle yields per participant pair increase from peripheral to midcentral and saturate at the most central collisions for all particle species. We also measure particle ratios of π-/π+, K -/K+, ̄p/p, K/π, p/π, and ̄p/π as a function of pT and collision centrality. The ratios of equal mass particle yields are independent of pT and centrality within the experimental uncertainties. In central collisions at intermediate transverse momenta ∼1.5-4.5 GeV/c, proton and antiproton yields constitute a significant fraction of the charged hadron production and show a scaling behavior different from that of pions.

    First results on charm quarkonia production in heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) are presented. The yield of J/ψ's measured in the PHENIX experiment via electron-positron decay pairs at midrapidity for Au-Au reactions at √SNN=200 GeV is analyzed as a function of collision centrality. For this analysis we have studied 49.3 × 106 minimum bias Au-Au reactions. We present the J/ψ invariant yield dN/dy for peripheral and midcentral reactions. For the most central collisions where we observe no signal above background, we quote 90% confidence level upper limits. We compare these results with our J/ψ measurement from proton-proton reactions at the same energy. We find that our measurements are not consistent with models that predict strong enhancement relative to binary collision scaling.

    Longitudinal density correlations of produced matter in Au+Au collisions at sNN=200 GeV have been measured from the inclusive charged particle distributions as a function of pseudorapidity window sizes. The extracted αξ parameter, related to the susceptibility of the density fluctuations in the long-wavelength limit, exhibits a nonmonotonic behavior as a function of the number of participant nucleons, Npart. A local maximum is seen at Npart~90, with corresponding energy density based on the Bjorken picture of εBjτ~2.4 GeV/(fm2c) with a transverse area size of 60 fm2. This behavior may suggest a critical phase boundary based on the Ginzburg-Landau framework. © 2007 The American Physical Society.

    The azimuthal distribution of identified π0 and inclusive photons has been measured in sNN=200GeV Au+Au collisions with the PHENIX experiment at the Relativistic Heavy-Ion Collider (RHIC). The second-harmonic parameter (v2) was measured to describe the observed anisotropy of the azimuthal distribution. The measured inclusive photon v2 is consistent with the value expected for the photons from hadron decay and is also consistent with the lack of direct photon signal over the measured pT range 1-6GeV/c. An attempt is made to extract v2 of direct photons. © 2006 The American Physical Society.

    The event-by-event fluctuations of the average transverse momentum of produced particles near mid-rapidity were measured using the PHENIX Collaboration in √SNN=20GeV Au + Au, and p+p collisions at the Relativistic Heavy Ion Collider. The fluctuations were in excess of the expectation for statistically independent particle emission for all centralities. The dependence on both, the centrality of the collision and on the pT range, over which the average is calculated, were exhibited by excess fluctuations. It is found that simulation of random particle production with addition of contributions from hard-scattering processes produces both, the centrality and pT dependence.

    The transverse momentum dependence of the azimuthal anisotropy parameter v2, the second harmonic of the azimuthal distribution, for electrons at midrapidity (|η|<0.35) has been measured with the PHENIX detector in Au+Au collisions at sNN=200 GeV. The measurement was made with respect to the reaction plane defined at high rapidities (|η|=3.1-3.9). From the result we have measured the v2 of electrons from heavy flavor decay after subtraction of the v2 of electrons from other sources such as photon conversions and Dalitz decay from light neutral mesons. We observe a nonzero single electron v2 with a 90% confidence level in the intermediate-pT region. The precision of the present data set does not permit us to conclude definitively that heavy quarks exhibit thermalization with the transverse flow of the bulk matter. © 2005 The American Physical Society.

    Muon production at forward rapidity (1.5≤|η|≤1.8) has been measured by the PHENIX experiment over the transverse momentum range 1≤pT≤3GeV/c in s=200GeV p+p collisions at the Relativistic Heavy Ion Collider. After statistically subtracting contributions from light hadron decays an excess remains which is attributed to the semileptonic decays of hadrons carrying heavy flavor, i.e. charm quarks or, at high pT, bottom quarks. The resulting muon spectrum from heavy flavor decays is compared to PYTHIA and a next-to-leading-order perturbative QCD calculation. PYTHIA is used to determine the charm quark spectrum that would produce the observed muon excess. The corresponding differential cross section for charm quark production at forward rapidity is determined to be dσcc̄/dy|y=1.6=0.243±0.013(stat.) ±0.105(datasyst.)+0.049-0.087(PYTHIAsyst.)mb. © 2007 The American Physical Society.

    A measurement of direct photons in p + p collisions at √s = 200 GeV is presented. A photon excess above background from π0 → γ + γ, η → γ + γ and other decays is observed in the transverse momentum range 5.5 < pT < 7 GeV/c. The result is compared to a next-to-leading-order perturbative QCD calculation. Within errors, good agreement is found between the QCD calculation and the measured result. © 2005 The American Physical Society.
