The ALICE (A Large Ion Collider Experiment) detector at the LHC is designed
to study the properties of Quark-Gluon Plasma (QGP), a deconfined state of
quarks and gluons produced in the ultrarelativistic heavy ions collisions.
Heavy-quarks, charm and beauty, are considered as effective probes for the
investigation of the QGP properties. Due to their large masses they are
produced almost exclusively during the hard-scattering phase and therefore
experience the full evolution of the collision, interacting and losing
energy in the hot and dense medium produced.

The study of angular correlations between D mesons and charged particles in
different collision systems provides information about the possible
medium-induced modification of charm quark fragmentation into jets. The same
study in the pp collision system, beside constituting the natural reference
to understand the results in p-Pb and Pb-Pb collisions systems, allows
investigating charm quark production mechanisms, fragmentation and

In this poster, the measurement of azimuthal correlations
between D$^0$ meson and charged particles in pp collisions at
$\sqrt{s} = 13$ TeV will be presented. The comparison with results obtained
at $\sqrt{s} = 7$ TeV allows investigating the dependence
of the result from the energy of the collision. The data will also be
compared with simulations results obtained with different event generators.
