Abstract
Heavy-flavour measurements give an important contribution to the understanding of the Quark-Gluon Plasma (QGP) produced in heavy-ion collisions. Heavy quarks are effective probes for the QGP and understanding their interaction with the medium can give insights into its transport properties. The ALICE Collaboration investigates heavy-flavour production by measuring leptons from heavy-flavour decays and by reconstructing hadronic decays of D mesons and charmed baryons. In this proceeding, recent results from ALICE as well as the direction of future heavy-flavour measurements are discussed.

The decay products can be identified using the signals of the Time Projection Chamber (TPC) and the Time Of Flight detector (TOF)
Summary
Heavy quarks – charm and beauty – are important tools to study the properties of the hot and dense matter produced in relativistic heavy–ion collisions. The study of their interaction with the medium can yield insight into its properties. Due to their large mass (mc/b ≈ 1.5/4.5 GeV/c), heavy quarks are produced almost exclusively in the initial hard scattering processes of the collision. The relative contribution of these processes differs between models It depends on the momentum and mass of the heavy quark. Measurements over a large momentum range for both flavours are needed to disentangle the contributions
