# Event-by-event $v_n$ correlations of soft hadrons and heavy mesons in heavy ion collisions

## TL;DR

This study combines event-by-event hydrodynamics with heavy quark energy loss to analyze correlations between soft and heavy mesons' flow harmonics in PbPb collisions, revealing different development times for $v_2$ and $v_3$.

## Contribution

It introduces a novel combined modeling approach to study event-by-event correlations of flow harmonics in heavy ion collisions.

## Key findings

- $v_3$ is strongly affected by fragmentation temperature.
- $v_3$ develops later than $v_2$ during system evolution.
- Correlations between heavy and soft sectors depend on flow harmonic and collision energy.

## Abstract

Combining event-by-event hydrodynamics with heavy quark energy loss we compute correlations between the heavy and soft sectors for elliptic and triangular flow harmonics $v_2$ and $v_3$ of D$^0$ mesons in PbPb collisions at $2.76$ TeV and $5.02$ TeV. Our results indicate that $v_3$ is strongly influenced by the fragmentation temperature and that it builds up later than $v_2$ during the evolution of the system.
