Abstract
We present the first forward-rapidity measurements of elliptic anisotropy of open-heavy-flavor muons at the Relativistic Heavy Ion Collider. The measurements are based on data samples of Au + Au collisions at √ sNN = 200GeV collected by the PHENIX experiment in 2014 and 2016 with integrated luminosity of 14.5nb−1. The measurements are performed in the pseudorapidity range 1.2 < |η| < 2 and cover transverse momenta 1 < pT < 4GeV/c. The elliptic flow of charged hadrons as a function of transverse momentum is also measured in the same kinematic range. We observe significant elliptic flow for both charged hadrons and heavy-flavor muons. The results show clear mass ordering of elliptic flow of light- and heavy-flavor particles. The... (More)
We present the first forward-rapidity measurements of elliptic anisotropy of open-heavy-flavor muons at the Relativistic Heavy Ion Collider. The measurements are based on data samples of Au + Au collisions at √ sNN = 200GeV collected by the PHENIX experiment in 2014 and 2016 with integrated luminosity of 14.5nb−1. The measurements are performed in the pseudorapidity range 1.2 < |η| < 2 and cover transverse momenta 1 < pT < 4GeV/c. The elliptic flow of charged hadrons as a function of transverse momentum is also measured in the same kinematic range. We observe significant elliptic flow for both charged hadrons and heavy-flavor muons. The results show clear mass ordering of elliptic flow of light- and heavy-flavor particles. The magnitude of the measured v2 is comparable to that in the midrapidity region. This indicates that there is no strong longitudinal dependence in the quark-gluon-plasma evolution between midrapidity and the rapidity range of this measurement at √ sNN = 200GeV © 2025 American Physical Society (Less)
