Abstract
The ALICE (A Large Ion Collider Experiment) detector at the LHC (Large Hadron Collider) is
designed to study the properties of Quark-Gluon Plasma (QGP), a deconfined state of quarks and
gluons produced in ultrarelativistic heavy ion collisions. The heavy quarks (charm and beauty) are
produced in the initial stages of the collisions due to their large masses. Hence, they experience the
evolution of the hot and dense medium created and act as an effective probe for its understanding.
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. In pp collisions, this measurement allows the study of the production
mechanisms, fragmentation and hadronization of charm quarks. In addition, it acts as a reference
for p–Pb and Pb–Pb systems.
In this article, the measurement of azimuthal correlations between D0 meson and charged particles
in pp collisions at
$\sqrt{s}$ = 13 TeV will be presented. The data will also be compared with
simulations results performed with different event generators.
