Description
The early production of heavy-flavour quarks, i.e. charm and beauty, in ultra-relativistic collisions makes them an excellent probe to study the evolution of the strongly interacting systems.
Jets tagged by the presence of heavy-flavour hadrons and correlation measurements involving heavy-flavour hadrons give a close access to the parton kinematics allowing comparisons of their production, propagation and fragmentation across different systems.
In this contribution, the measurements of the fragmentation function of jets containing fully reconstructed D$^{0}$ mesons and $\rm{\Lambda^{+}_{c}}$ baryons in pp collisions will be presented. The first observation of dead-cone effect impacting heavy-flavour parton showers will be discussed with the measurement of D$^{0}$-tagged jets in pp collisions. The partons are expected to lose energy while traversing through the QGP medium at a different rate to their inclusive counterparts. To address the effects of in-medium energy loss, measurements of the nuclear modification factor of D$^{0}$ meson-tagged jets will be presented in the $0-10\%$ most central Pb$-$Pb collisions.
In order to have a deeper insight of charm-quark fragmentation, the measurements of azimuthal correlations between D mesons and charged particles will be presented in both pp and p$-$Pb collisions. The measurements in p$-$Pb collisions are important to probe the impact of cold nuclear matter effects while pp collisions serve as a validating tool for Monte-Carlo models along with providing a baseline for future Pb$-$Pb measurements. The discussion will be carried forward by presenting an evaluation of the performance of D$^{0}$$-$$\bar{\mathrm{D}}^{0}$ correlation studies based on simulations for ALICE 3.
