Kinematic dependence of azimuthal anisotropies in p plus Au, d + Au, and 3He +Au at √sNN=200 GeV

There is strong evidence for the formation of small droplets of quark-gluon plasma in p/d/ He-3 +Au collisions at the Relativistic Heavy Ion Collider (RHIC) and in p + p/Pb collisions at the Large Hadron Collider. In particular, the analysis of data at RHIC for different geometries obtained by varying the projectile size and shape has proved insightful. In the present analysis, we find excellent agreement with the previously published PHENIX at RHIC results on elliptical and triangular flow with an independent analysis via the two-particle correlation method, which has quite different systematic uncertainties and an independent code base. In addition, the results are extended to other detector combinations with different kinematic (pseudorapidity) coverage. These results provide additional constraints on contributions from nonflow and longitudinal decorrelations.

Independent analysis using the two-particle correlation method has shown excellent agreement with previously published results on elliptical and triangular flow. These findings extend to other detector combinations with different kinematic coverage and provide additional constraints on nonflow contributions and longitudinal decorrelations.
