# Measurements of the suppression and anisotropy of heavy-flavour particles in Pb--Pb collisions at $\sqrt{s_\mathrm{NN}}$= 2.76 TeV with ALICE

## TL;DR

This paper reports on measurements of heavy-flavour particle suppression and anisotropy in lead-lead collisions at 2.76 TeV, providing insights into how heavy quarks interact with the quark-gluon plasma.

## Contribution

It presents new experimental results on heavy-flavour production, suppression, and flow in Pb--Pb collisions at 2.76 TeV using ALICE data.

## Key findings

- Heavy-flavour particles show significant suppression in Pb--Pb collisions.
- Elliptic flow ($v_2$) indicates strong interaction with the medium.
- Results help understand parton energy loss and thermalization processes.

## Abstract

Heavy quarks, i.e. charm and beauty, are produced on a shorter time scale with respect to the strongly-interacting matter produced in high-energy heavy-ion collisions. Therefore, they are unique probes to study the mechanisms of parton energy loss, hadronisation and thermalization in the hot and dense state of matter. The nuclear modification factor ($R_{\rm AA}$) and the elliptic flow ($v_{2}$) are two of the main experimental observables that allow us to investigate the interaction strength of heavy quarks with the medium. The most recent results on heavy-flavour production and elliptic flow measured by the ALICE collaboration in Pb--Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 2.76 TeV will be discussed.
