Heavy-flavour productions in the relativistic heavy ion collisions in LHC

In the Large Hadron Collider (LHC), open heavy-flavour productions in the heavy-ion collisions (Pb–Pb) has studied by measuring D mesons, leptons from semi-leptonic decay of heavy-flavour hadrons and jets which are original from heavy quarks. In this proceedings, those results are shown together with the measurements with pp and p-Pb collisions and discussed with theoretical calculations to understand the properties of the QCD matter.
