Azimuthal anisotropy in U+U collisions at STAR

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...

Azimuthal anisotropy in Au plus Au collisions at root S-NN=200 GeV

Azimuthal anisotropy of φ meson in U+U and Au+Au collisions at RHIC

The measurements of the azimuthal anisotropy of φ meson in the U+U and Au+Au collisions at the Relativistic Heavy-Ion Collider (RHIC) are reported. The centrality dependence of the Fourier coefficients v2, v3, v4 and v5 is presented for φ meson at midrapidity (|η| ≤ 1.0), in U+U and Au+Au collisions at sNN = 193 and 200 GeV, respectively. The η-sub event plane method is used with a η gap of 0.1...

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...

Measurement of higher-order harmonic azimuthal anisotropy in PbPb collisions at √ sNN = 2.76 TeV

Measurements are presented by the CMS Collaboration at the Large Hadron Collider (LHC) of the higher-order harmonic coefficients that describe the azimuthal anisotropy of charged particles emitted in √ sNN = 2.76 TeV PbPb collisions. Expressed in terms of the Fourier components of the azimuthal distribution, the n = 3–6 harmonic coefficients are presented for charged particles as a function of ...
