Scaling properties of azimuthal anisotropy of mesons and baryons at RHIC
Detailed measurements of the azimuthal anisotropy (2̌) for identified charged particles are reported as a function of transverse momentum (pT ) and centrality for Au+Au collisions at √ sNN =200 GeV. The measurements indicate clear evidence for eccentricity and particle flavor scaling over a broad range of centralities and transverse rapidity yT , indicating a hydrodynamical origin of the fine st...
متن کاملHigh-pT azimuthal correlations of neutral strange baryons and mesons in STAR at RHIC
We present results on two-particle azimuthal correlations of high-pT neutral strange baryons (Λ,Λ̄) and mesons (K0 S ) associated with non-identified charged particles in d+Au and Au+Au collisions at √ sNN = 200 GeV. In particular, we discuss properties of the near-side yield of associated charged particles as a function of centrality, transverse momentum and zT , as well as possible baryon/meso...
متن کاملTwo-particle correlations with strange baryons and mesons at RHIC
We present results on two-particle correlations using singly-strange particles (Λ, Λ̄, K S) and charged hadrons at intermediate pT in d+Au and Au+Au collisions at RHIC. We discuss properties of the near-side correlation peak in both azimuthal and pseudo-rapidity space and separate jet-like contributions from the long-range pseudo-rapidity correlations (the ridge). In particular, we study the cen...
متن کاملAzimuthal anisotropy and fundamental symmetries in QCD matter at RHIC
A study of collective behavior in heavy ion collisions provides one of the most sensitive and promising probes for investigation of possible formation of new extreme state of strong interacting matter and elucidating its properties. Systematic of experimental results for final state azimuthal anisotropy is presented for heavy ion interactions at RHIC. Experimental data for azimuthal anisotropy ...
متن کاملIdentified charged particle azimuthal anisotropy in PHENIX at RHIC
Event anisotropy is expected to have sensitivity to the early stage of ultra-relativistic heavy-ion collisions at RHIC. The possible formation of a quark gluon plasma (QGP) could affect how the initial anisotropy in the space coordinate is transferred into the momentum space for the final state. The anisotropy parameter (v2) is an amplitude of the 2nd harmonic parameter of the azimuthal distrib...
