Identified charged hadron production in p + p collisions at √ s = 200 and 62.4 GeV
Transverse momentum distributions and yields for pi(+/-), K-+/-, p, and (p) over bar in p + p collisions at root s = 200 and 62.4 GeV at midrapidity are measured by the PHENIX experiment at the… Expand
J/ψ suppression at forward rapidity in Au + Au collisions at √sNN=200 GeV
Heavy quarkonia are observed to be suppressed in relativistic heavy-ion collisions relative to their production in p + p collisions scaled by the number of binary collisions. In order to determine if… Expand

For Au + Au collisions at 200 GeV, neutral pion production is measured with good statistics for transverse momentum, pT, and a fivefold suppression is found, which is essentially constant for 5 < pT < 20 GeV/c. Expand
Spectra and ratios of identified particles in Au+Au and d+Au collisions at √sNN=200 GeV
The transverse momentum (p(T)) spectra and ratios of identified charged hadrons (pi(+/-), K-+/-, p, (p) over bar) produced in root s(NN) = 200 GeV Au + Au and d + Au collisions are reported in five… Expand
Absence of suppression in particle production at large transverse momentum in sqrt[s(NN)]=200 GeV d+Au collisions.
The yield ratio does not show the suppression observed in central Au+Au collisions at RHIC, but there is a small enhancement in the yield of high momentum particles. Expand
Observation of direct-photon collective flow in sqrt(s_NN)=200 GeV Au+Au collisions
The second Fourier component v_2 of the azimuthal anisotropy with respect to the reaction plane was measured for direct photons at midrapidity and transverse momentum (p_T) of 1--13 GeV/c in Au+Au… Expand
Measurements of higher order flow harmonics in Au+Au collisions at √s(NN)=200 GeV.
The ν(n) is reported as a function of transverse momentum and collision centrality, and the correlations among the event planes of different order n are studied to improve the precision of the extracted shear viscosity to entropy density ratio η/s. Expand
Scaling properties of azimuthal anisotropy in Au+Au and Cu+Cu Collisions at sqrt[s NN]=200 GeV.
Quark number scaling reveals a universal scaling of v2 for both mesons and baryons over the full KE T range for Au+Au and Cu+Cu, which is compatible with hydrodynamic expansion of a thermalized fluid. Expand
Azimuthal anisotropy of π0 production in Au+Au collisions at √sNN=200GeV: Path-length dependence of jet quenching and the role of initial geometry
We have measured the azimuthal anisotropy of pi(0) production for 1 < p(T) < 18 GeV/c for Au + Au collisions at root s(NN) = 200 GeV. The observed anisotropy shows a gradual decrease for 3 less than… Expand
