Description
In this work we investigate how event-by-event hydrodynamic fluctuations affect the nuclear suppression factor and elliptic flow of heavy flavor mesons and non-photonic electrons. Local temperature and flow profiles are computed using a 2D+1 Lagrangian ideal hydrodynamic code [1] on an event-by-event basis. We use a strong coupling inspired energy loss parametrization [2] on top of the evolving space-time energy density distributions to propagate the heavy quarks inside the medium until the freeze-out temperature is reached and hadronization (modeled using PYTHIA) takes place. The resulting D$^0$ and non-photonic electron yield, computed event by event [6], is compared with recent experimental data for $R_\text{AA}$ and $v_2$ from the STAR and PHENIX collaborations [3-5]. We also present predictions for the higher order Fourier harmonic coefficients $v_3(p_T)$ and $v_4(p_T)$ of non-photonic electrons at RHIC's $\sqrt{s}=200$ GeV/n collisions.
