Abstract

Global polarization of Λ hyperons has been measured to be of the order of a few tenths of a percent in Au+Au collisions at √ ^S _NN = 200 GeV, with no significant difference between Λ and Λ¯. These new results reveal the collision energy dependence of the global polarization together with the results previously observed √ ^S _NN = 7.7 – 62.4 GeV and indicate noticeable vorticity of the medium created in non-central heavy-ion collisions at the highest RHIC collision energy.

Measurement of K ⁰ _S and K ^*0 in p+p, d+Au, and Cu+Cu collisions at sqrt S _NN = 200 GeV

Journal Article Adare, A. ; Aidala, C. - Physical Review. C, Nuclear Physics

The PHENIX experiment at the Relativistic Heavy Ion Collider has performed a systematic study of K ⁰ _S and K ^*0 meson production at midrapidity in p+p, d+Au, and Cu+Cu collisions at sqrt S _NN = 200 GeV. The K ⁰ _S and K ^*0 mesons are reconstructed via their K ⁰ _S and π ⁰(→γγ)π ⁰ (→γγ) and K ^*0 → K ^±π ^± decay modes, respectively. The measured transverse-momentum spectra are used to determine the nuclear modification factor of K ⁰ _S and K ^*0 mesons in d+Au and Cu+Cu collisions at different centralities.

Measurements of elliptic and triangular flow in high-multiplicity ³He+Au collisions at √s _NN=200 GeV

Journal Article Adare, A. - Physical Review Letters

We present the first measurement of elliptic (v ₂) and triangular (v ₃) flow in high-multiplicity ³He+Aucollisions at √s _NN=200 GeV. Two-particle correlations, where the particles have a large separation in pseudorapidity, are compared in ³He+Au and in p+p collisions and indicate that collective effects dominate the second and third Fourier components for the correlations observed in the ³He+Ausystem. The collective behavior is quantified in terms of elliptic v ₂ and triangular v ₃ anisotropy coefficients measured with respect to their corresponding event planes. The v ₂ values are comparable to those previously measured in d+Au collisions at the samemore »« less

Azimuthal anisotropy of K ⁰ _s and Λ + Λ¯¯¯ production at mid-rapidity from Au+Au collisions at √( ^sNN) = 130 GeV.

Journal Article Adler, C. ; Ahammed, Z. ; Allgower, C. ; ... - Physical Review Letters

We report STAR results on the azimuthal anisotropy parameter v₂ for strange particles K ⁰ _s, Λ, and Λ⁻ at midrapidity in Au+Au collisions at √( ^sNN)=130 GeV at the Relativistic Heavy Ion Collider. The value of v₂ as a function of transverse momentum, p _t, of the produced particle and collision centrality is presented for both particles up to p _t~3.0 GeV/c. A strong p _t dependence in v₂ is observed up to 2.0 GeV/c. The v₂ measurement is compared with hydrodynamic model calculations. The physics implications of the p _t integrated v₂ magnitude as a function of particlemore » mass are also discussed.« less
