L. Adamczyk, G. Agakishiev, M. M. Aggarwal +368
We report on mid-rapidity mass spectrum of di-electrons and cross sections of pseudoscalar and vector mesons via decays, from GeV collisions, me…
Anisotropic Flow in sqrt(s_NN) = 200 GeV Cu+Cu and Au+Au collisions at PHENIX
H. Masui
We report the measurement of anisotropic flow at RHIC - PHENIX experiment. We present the v_4 results at sqrt(s_NN) = 200 GeV in Au+Au collision. The scaling ratio of v_4/(v_2)^2 i…
Energy and system-size dependence of two- and four-particle measurements in heavy-ion collisions at RHIC and their implications on flow fluctuations and nonflow
The STAR Collaboration, G. Agakishiev, M. M. Aggarwal +344
We present STAR measurements of azimuthal anisotropy by means of the two- and four-particle cumulants ( and ) for Au+Au and Cu+Cu collisions at center of…
Inclusive double-helicity asymmetries in neutral pion and eta meson production in collisions at GeV
A. Adare, C. Aidala, N. N. Ajitanand +377
Results are presented from data recorded in 2009 by the PHENIX experiment at the Relativistic Heavy Ion Collider for the double-longitudinal spin asymmetry, , for an…
Quadrupole Anisotropy in Dihadron Azimuthal Correlations in Central Au Collisions at =200 GeV
A. Adare, C. Aidala, N. N. Ajitanand +373
The PHENIX collaboration at the Relativistic Heavy Ion Collider (RHIC) reports measurements of azimuthal dihadron correlations near midrapidity in Au collisions at $\sqrt{s_{…
Erratum: Measurement of transverse single-spin asymmetries for J/psi production in polarized p+p collisions at sqrt(s)=200 GeV [Phys. Rev. D 82, 112008 (2010)]
A. Adare, S. Afanasiev, C. Aidala +444
We previously reported [Phys. Rev. D 82, 112008 (2010)] measurements of transverse single-spin asymmetries, A_N, in J/psi production from transversely polarized p+p collisions at s…
