Description
One of the most prominent features of the quark gluon plasma is its near-perfect
fluid behavior. An important outstanding question is establishing the degree to which
heavy flavor particles flow with the bulk system. Measurements of the Fourier coefficient
v2 of light and heavy flavor hadrons can provide insight into the properties of the
medium. At low transverse momentum (pT) the mass dependence of v2
is associated
with the common flow velocity in the bulk system, whereas at higher pT path length and
mass dependencies in the energy loss play a role. We will present new results
measured with the PHENIX muon arms covering 1.2<|η|<2.2 using high statistics
Au+Au dataset collected in 2014. The v2 of light hadrons and muons from heavy flavor
decays are measured in the range 0.5<pT<5 GeV/c and the results are compared to
measurements at mid-rapidity. Forward rapidity samples different initial and final state
effects than mid-rapidity, and therefore the produced particles may be subject to
different pressure gradients. The measurements will be compared to theoretical
calculations.
