Description
Heavy quarks (charm and beauty) are produced in hard parton scatterings in the early stages 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. The study of angular correlations between heavy-flavour particles and charged particles allows us to characterize the heavy-quark fragmentation process and its possible modification in a hot and dense medium. The measurement of heavy-flavour jets gives more direct access to the initial parton kinematics and can provide further constraints for heavy-quark energy-loss models, in particular adding information on how the radiated energy is dissipated in the medium.
Studies in pp collisions are mandatory to characterize heavy-quark production and fragmentation in vacuum, constituting the necessary reference for interpreting heavy-ion collision results. Differences between results from pp and p-Pb collisions can reflect how the heavy-quark production and hadronization into jets is affected by cold nuclear matter effects.
This contribution will include the latest heavy-flavour correlation and jet measurements with the ALICE detector in pp, p-Pb and Pb-Pb collisions from the LHC Run-2 data. In particular, results on azimuthal correlations of D mesons with charged particles in p-Pb collisions at $\sqrt{{s}_{\rm{NN}}} = 5.02$ TeV will be presented. Measurements of multiplicity and centrality dependent azimuthal correlations of heavy-flavour hadron decay electrons with charged particles in p-Pb and Pb-Pb collisions at $\sqrt{{s}_{\rm{NN}}} = 5.02$ TeV will be shown. In addition, measurements of D-meson tagged and beauty tagged jet production in pp collisions at $\sqrt{s} = 7$ TeV and p-Pb collisions at $\sqrt{{s}_{\rm{NN}}} = 5.02$ TeV will be presented. The status of D-tagged jet measurements in Pb-Pb collisions at $\sqrt{{s}_{\rm{NN}}} = 5.02$ TeV will be discussed.
