Energy and system size dependent heavy flavor measurements at PHENIX at RHIC

Abstract

Heavy flavor production is an ideal tool to study the properties of the Quark Gluon Plasma (QGP). The heavy flavor production at the Relativistic Heavy Ion Collider (RHIC) has its unique kinematic coverage and different production mechanisms from the Larger Hadron Collider (LHC) measurements. Heavy flavor products created in heavy ion collisions experience the whole evolution of nuclear medium. It's critical to measure both open and closed heavy flavor products in different collision systems to isolate cold/hot nuclear medium effects and initial/final state interactions. We report recent heavy flavor measurements at PHENIX in 200 GeV $p$+$p$, $p$+Al, $p$+Au, $^{3}$He+Au and Au+Au collisions that include: the correlated di-muon analysis in 200 GeV $p$+$p$ and $p$+Au collisions; the rapidity and $N_{part}$ dependent $J/\psi$ $R_{AB}$ measured in asymmetric small systems; open heavy flavor $v_{2}$ measured in 200 GeV d+Au and Au+Au collisions. These measurements provide further information about the heavy flavor production mechanism, initial and final state nuclear modification and flavor dependent energy loss in QGP.
