Heavy flavor $R_\text{AA}$ and $v_n$ in event-by-event viscous relativistic hydrodynamics

TL;DR

This paper explores how event-by-event viscous hydrodynamics affects heavy flavor meson suppression and flow coefficients in high-energy PbPb collisions, providing insights into the medium's fluctuating properties.

Contribution

It extends viscous hydrodynamics modeling to heavy flavor observables, incorporating full event-by-event fluctuations for more realistic predictions.

Findings

Event-by-event fluctuations significantly influence heavy flavor $v_2$ and $v_3$.

Hydrodynamic backgrounds impact the nuclear suppression factor $R_{AA}$ for heavy flavors.

Results show consistency with experimental data for flow coefficients at LHC energies.

Abstract

Recently it has been shown that a realistic description of the medium via event-by-event viscous hydrodynamics plays an important role in the long-standing $R_\text{AA}$ vs. $v_2$ puzzle at high $p_T$. In this proceedings we begin to extend this approach to the heavy flavor sector by investigating the effects of full event-by-event fluctuating hydrodynamic backgrounds on the nuclear suppression factor and $v_2\{2\}$ of heavy flavor mesons and non-photonic electrons at intermediate to high $p_T$. We also show results for $v_3\{2\}$ of $B^0$ and D$^0$ for PbPb collisions at $\sqrt{s}=2.76$ TeV.
