Název v původním jazyce

Measurements at forward rapidity of elliptic flow of charged hadrons and open-heavy-flavor muons in Au plus Au collisions at √sNN=200 GeV

Popis výsledku v původním jazyce

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 root s(NN) = 200 GeV collected by the PHENIX experiment in 2014 and 2016 with integrated luminosity of 14.5 nb(-1). The measurements are performed in the pseudorapidity range 1.2 &lt; vertical bar eta vertical bar &lt; 2 and cover transverse momenta 1 &lt; p(T) &lt; 4 GeV/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 v(2) 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 root s(NN) = 200 GeV.
