Azimuthal Anisotropy of Identified Hadrons in 200 GeV Au+Au Collisions

Azimuthal Anisotropy of Identified Hadrons in 200 GeVAu + Au Collisions

The azimuthal anisotropy parameter v 2 has been measured with high statistics for identified hadrons in √ s N N = 200 GeV Au+Au collisions with the STAR experiment. At high transverse momentum (p T) a strong v 2 for π + + π − and p + p is observed. In the intermediate p T region, number-of-constituent-quark scaling was tested to high precision. A detailed comparison of v 2 for the multi-strange...

Pion Interferometry in Auau Collisions at √ S Nn =200 Gev

We present preliminary results from a two-pion intensity interferometry analysis from Au+Au collisions at √ s NN =200 GeV measured in the STAR detector at RHIC. The dependence of the apparent pion source on multiplicity and transverse momentum are discussed and compared with preliminary results from d+Au and p+p collisions at the same beam energy.

Azimuthal Anisotropy of Charged and Identified High pT Hadrons in Au+Au Collisions at RHIC

We report new results on v2(pT ) for Au+Au collisions at √ sNN=200 GeV for charged hadrons, pions, kaons, (anti)protons, K s , and Λ. The analysis is extended to pT = 12 GeV/c for charged hadrons and pT = 4 GeV/c for identified particles. A comparison of the azimuthal anisotropy of charged hadrons measured at √ sNN=130 and 200 GeV is presented. The pT -dependence of baryon versus meson elliptic...
