(Anti)nuclei production in ALICE — •Rafael Manhart for the ALICE Germany collaboration — Technische Universität München
High-energy hadronic collisions at accelerators create a suitable environment for the production of light (anti)(hyper)nuclei. Precise measurements of the antinuclei production at accelerators are essential to study the different sources of antinuclei in our Universe and to correctly interpret any future measurement of antinuclei in space. (Anti)nuclei production measurements are also interesting to investigate their production mechanisms, which are under intense debate in the scientific community. The description of the experimental measurements is currently based on two competing phenomenological models: the statistical hadronisation model and the coalescence approach. The production of (anti)nuclei, up to A=4, has been measured with ALICE in the last 10 years, from small collision systems (i.e., pp and p*Pb) to heavy-ion collisions (i.e., Xe*Xe and Pb*Pb). In 2022, LHC Run 3 has started and pp collisions at top centre-of-mass energy of √s = 13.6 TeV have been recorded with the unprecedented luminosity of 18 pb−1. In this contribution, new measurements of (anti)nuclei from Run 3 data will be shown, together with a review of (anti)nuclei results from Run 1 and 2.
