Heavy-flavour measurements in Pb-Pb collisions with ALICE at the LHC

The ALICE experiment studies the properties of the strongly-interacting matter created in high energy heavy-ion collisions, called Quark-Gluon Plasma (QGP). Heavy quarks are a powerful probe for investi- gating such a state of matter, since they are predominantly produced in the first hard scattering processes and they bring to the final state information on the deconfined phase. Heavy-flavour particles are reconstructed via hadronic and semi-leptonic decays in the ALICE detector. The measurements of the modification of the heavy- flavour hadrons transverse momentum distribution in Pb–Pb collisions with respect to pp and of their azimuthal anisotropy show that heavy quarks have a sizeable interaction with the medium constituents.
