# Transport properties from Charm to Bottom: $p_T$ suppression, anisotropic flow $v_n$ and their correlations to the bulk dynamics

## TL;DR

This paper models heavy quark propagation in quark-gluon plasma using a relativistic Boltzmann approach, successfully describing experimental data and predicting B meson suppression, while exploring flow correlations and initial state effects.

## Contribution

It introduces a non-perturbative quasi-particle model within a relativistic Boltzmann framework to describe heavy quark interactions and flow observables across RHIC and LHC energies.

## Key findings

- Successfully describes D meson $R_{AA}$ and $v_2$ data from RHIC to LHC
- Predicts B meson $R_{AA}$ at LHC energies
- Highlights the importance of initial state fluctuations in flow correlations

## Abstract

We study the propagation of heavy quarks (HQs) in the quark-gluon plasma (QGP) by means of a relativistic Boltzmann transport (RBT) approach. The non-perturbative interaction between heavy quarks and light quarks is described by means of a quasi-particle approach able to describe simultaneously the experimental data for the nuclear suppression factor $R_{\rm AA}$ and the elliptic flow $v_2(p_T)$ of D mesons from RHIC to LHC energies. In the same framework we predict the B meson nuclear modification factor at LHC. Finally, we discuss the relevance of initial state fluctuations that allows to extend the analysis to high order anisotropic flows $v_n(p_T)$ as well as to investigate the role of QCD interaction in developing correlations between the light and the heavy flavour anisotropic flows.
