# Open Heavy Flavour: Experimental summary

## TL;DR

This paper reviews recent experimental measurements of heavy-flavour hadrons from RHIC and LHC, highlighting open questions about heavy quarks in different collision systems to understand quark-gluon plasma properties.

## Contribution

It summarizes recent experimental results on heavy-flavour hadrons and discusses open questions and future measurements in heavy-ion collision research.

## Key findings

- Open heavy-flavour measurements reveal insights into QGP properties.
- Discrepancies in small and large collision systems highlight unresolved issues.
- Experimental data from RHIC and LHC inform ongoing theoretical models.

## Abstract

In this paper I will review a few of the latest experimental measurements of heavy-flavour hadrons presented at the Hard Probes 2018 conference. Results from experiments both at RHIC and at the LHC will be discussed. I will present some of the open questions that still need to be addressed with heavy quarks in small collision systems and in A-A collisions, to better understand the properties of the QGP produced in heavy-ion collisions. I will discuss some of the open heavy-flavour measurements designed to give insights into these questions.
