Abstract (data abstract)

BNL-RHIC. Measurements of azimuthal dihadron correlations near midrapidity in d+Au collisions at sqrt(sNN) = 200 GeV recorded in 2008 by the PHENIX collaboration at the Relativistic Heavy Ion Collider (RHIC). These measurements complement recent analyses by experiments at the Large Hadron Collider (LHC) involving central p+Pb collisions at sqrt(sNN) = 5.02 TeV, which have indicated strong anisotropic long-range correlations in angular distributions of hadron pairs. Qualitatively similar, but larger, anisotropies are observed in d+Au collisions compared to those seen in p+Pb collisions at the LHC. The larger extracted v2 values in d+Au collisions at RHIC are consistent with expectations from hydrodynamic calculations owing to the larger expected initial-state eccentricity compared with that from p+Pb collisions. When both are divided by an estimate of the initial-state eccentricity, the scaled anisotropies follow a common trend with multiplicity that may extend to heavy ion data at RHIC and the LHC, where the anisotropies are widely thought to arise from hydrodynamic flow.
