Erratum: Disappearance of partonic collectivity in √ sNN = 3 GeV Au+Au collisions at RHIC [Phys. Lett. B 827, 137003 (2022)]

We report on the measurements of directed flow v 1 and elliptic flow v 2 for hadrons ( π ± , K ± , K S 0 , p , ϕ , Λ and Ξ − ) from Au+Au collisions at s N N = 3 GeV and v 2 for ( π ± , K ± , p and p ‾ ) at 27 and 54.4 GeV with the STAR experiment. While at the two higher energy midcentral collisions the number-of-constituent-quark (NCQ) scaling holds, at 3 GeV the v 2 at midrapidity is negative for all hadrons and the NCQ scaling is absent. In addition, the v 1 slopes at midrapidity for almost all observed hadrons are found to be positive, implying dominant repulsive baryonic interactions. The features of negative v 2 and positive v 1 slope at 3 GeV can be reproduced with a baryonic mean-field in transport model calculations. These results imply that the medium in such collisions is likely characterized by baryonic interactions.

Abstract

We report on the measurements of directed flow v 1 and elliptic flow v 2 for hadrons ( π ± , K ± , K S 0 , p , ϕ , Λ and Ξ − ) from Au+Au collisions at s N N = 3 GeV and v 2 for ( π ± , K ± , p and p ‾ ) at 27 and 54.4 GeV with the STAR experiment. While at the two higher energy midcentral collisions the number-of-constituent-quark (NCQ) scaling holds, at 3 GeV the v 2 at midrapidity is negative for all hadrons and the NCQ scaling is absent. In addition, the v 1 slopes at midrapidity for almost all observed hadrons are found to be positive, implying dominant repulsive baryonic interactions. The features of negative v 2 and positive v 1 slope at 3 GeV can be reproduced with a baryonic mean-field in transport model calculations. These results imply that the medium in such collisions is likely characterized by baryonic interactions.
