Description
Heavy quarks (charm and beauty) are ideal probes to investigate the properties of the Quark-Gluon Plasma (QGP) produced in ultra-relativistic heavy-ion collisions, being produced in hard-parton scatterings in the collision early stages and experiencing the whole QGP evolution.
Measurements of heavy-flavour jets give a direct access to the initial parton kinematics and can provide constraints to 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 characterise 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 are 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.
Measurements of azimuthal D meson-charged particle correlations, jets tagged with D mesons and jet-momentum fraction carried by the D meson will be presented in pp collisions at $\sqrt{s} = 5.02$, $7$ and $13$ TeV and compared with expectations from various Monte Carlo event generators.
Production of heavy-flavour jets in pp collisions at $\sqrt{s} = 5.02$ TeV will be also addressed with studies of charged jets tagged by heavy-flavour hadron decay electrons and beauty secondary vertices.
The nuclear modification factor in p--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV of the aforementioned heavy-flavour tagged jets will be also presented and complemented with measurement of the D-tagged jet nuclear modification factor in Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV.
