Measurement of azimuthal correlations of D\textsuperscript{0} mesons with charged particles in pp collisions at $\sqrt{s}$ = 5 TeV and 13 TeV with ALICE at the LHC
The ALICE (A Large Ion Collider Experiment) detector at the LHC is dedicated to the study the properties of the hot and dense QCD matter (Quark Gluon Plasma) produced in the nucleus-nucleus collisions at high energy. The heavy quarks (charm and beauty), having large masses, are produced in the hard-parton scattering in the early stages of the collisions. Therefore, they experience the whole evolution of the hot and dense medium, representing an important tool for its characterization. The study of angular correlations between D mesons and charged particles in Pb-Pb collisions give insight about the energy loss of charm quark and the medium-induced modification of its fragmentation into jets. Moreover, pp collisions help understanding the production mechanisms, fragmentation and hadronization of charm quarks and acts as a reference for p--Pb and Pb--Pb measurements. In this article, the measurement of azimuthal correlations between $\rm D^0$ meson and charged particles for pp collisions at $\sqrt{s} = 5$ TeV and 13 TeV are presented. The data are also compared with simulations results performed with different Monte Carlo event generators.
