Abstract
The formation mechanism of light (anti)nuclei produced in highenergy hadronic collisions is an open question that is being addressed both theoretically and experimentally. Moreover, the study of (anti)nuclei production at particle accelerators is relevant to model the flux of antinuclei produced in cosmic ray interactions, which represents the dominant background for dark matter searches. According to the most accredited theoretical models, dark matter particles in the galactic halo could annihilate and produce ordinary matter-antimatter pairs. Thanks to its excellent particle identification capabilities, ALICE measured (anti)nuclei in all the collision systems and energies provided by the LHC. Measurements of transverse momentum distributions, ratios of integrated yields, and coalescence probabilities are discussed in these proceedings in comparison with two phenomenological models used to describe the production of nuclei. The performance of the upgraded ALICE detector during the proton proton data taking in Run 3 is discussed together with perspectives on new applications to indirect dark matter searches by the AMS experiment.
