### Description

ALICE 3 is a next-generation heavy-ion experiment for LHC Run 5, which will
address physics questions that are not accessible with Runs 3 and 4. One of the main goals of ALICE3 is to understand the connection between heavy quark heavy quark transport and hadronisation. One such example is the measurement of azimuthal correlations between charm and anti-charm mesons. ALICE 3 would provide unique access to this topics and open up new possibilities in other areas too.

In this poster we will present an evaluation of the performance for $\mathrm{D^0-\bar{D}^0}$ correlation studies based on a simulated analysis in ALICE 3. The measurement of azimuthal angle correlations of charm particles provides unique information on the production and transport of charm quarks in the QGP. These methods will be applicable in $\mathrm{pp}$ as well as $\mathrm{A-A}$ collisions. We will also show in details the fitting procedure of 2D distribution of the $\mathrm{D^0-\bar{D}^0}$ invariant mass pairs.
