Analysis of heavy-flavour particles in ALICE with the O$^2$ analysis framework

Precise measurements of heavy-flavour hadrons down to very low $p$$_{T}$ represent the core of the physics program of the upgraded ALICE experiment in Run 3. These physics probes are characterised by a very small signal-to-background ratio requiring very large statistics of minimum-bias events. In Run 3, ALICE is expected to collect up to 13 nb$^{−1}$ of lead–lead collisions, corresponding to about 1 × 10$^{11}$ minimum-bias events. In order to analyse this unprecedented amount of data, which is about 100 times larger than the statistics collected in Run 1 and Run 2, the ALICE collaboration is developing a complex analysis framework that aims at maximising the processing speed and data volume reduction. In this paper, the strategy of reconstruction, selection, skimming, and analysis of heavy-flavour events for Run 3 will be presented. Some preliminary results on the reconstruction of charm mesons and baryons will be shown and the prospects for future developments and optimisation discussed.
