Heavy flavor electron $R_\text{AA}$ and $v_2$ in event-by-event relativistic hydrodynamics
Abstract
In this work we investigate how event-by-event hydrodynamics fluctuations affect the nuclear suppression factor and elliptic flow of heavy flavor mesons and non-photonic electrons. We use a 2D+1 Lagrangian ideal hydrodynamic code on an event-by-event basis in order to compute local temperature and flow profiles. Using a strong coupling inspired energy loss parametrization on top of the evolving space-time energy density distributions we are able to propagate the heavy quarks inside the medium until the freeze-out temperature is reached and a Pythia modeling of hadronization takes place. The resulting D and heavy-flavor electron yield is compared with recent experimental data for and from the STAR and Phenix collaborations. In addition we present preditions for the higher order Fourier harmonic coefficients of heavy-flavor electrons at RHIC's GeV collisions.
