Description
Heavy quarks (charm and beauty) are produced in hard parton scatterings in the early stage of hadronic collisions. Therefore, they are ideal probes to investigate the properties of the Quark-Gluon Plasma (QGP) produced in ultra-relativistic heavy-ion collisions. Measurements of heavy-flavour jets give a direct access to the initial parton kinematics and can provide constraints for heavy-quark energy-loss models, in particular adding information on how the radiated energy is dissipated in the medium. Studies of angular correlations between heavy-flavour particles and charged particles allow us to characterize the heavy-quark fragmentation process and its possible modification in a hot nuclear matter environment.
Measurements in pp collisions provide the necessary reference for the interpretation of heavy-ion collision results, allowing us to characterize the heavy-quark production and fragmentation in vacuum. Studies in p-Pb collisions give insight on how the heavy-quark production and hadronisation into jets is affected by the cold nuclear matter effects.
This contribution will focus on the latest studies of heavy-flavour jets and D-meson correlations with charged particles with the ALICE detector in pp collisions at $\sqrt{s}_{\rm NN} = 5.02$, 7, 13 TeV and in p-Pb and Pb-Pb collisions at $\sqrt{s}_{\rm NN} = 5.02$ TeV. In particular, the azimuthal correlations between D mesons and charged particles in pp and p-Pb collisions will be compared with various Monte Carlo event generators.
Production of charged jets tagged with D mesons and heavy-flavour hadron decay electrons will be reported in pp and p-Pb collisions. In addition, recent studies of the jet-momentum fraction carried by the D meson in pp collisions will be presented. Measurements of the nuclear modification factor of heavy-flavour jets in p-Pb and Pb-Pb collisions will be also discussed.
