He-3 inelastic cross section & nuclei production in Run3 — •Rafael Manhart for the ALICE Germany collaboration — Technische Universität München
This study focuses on two areas of nuclear and particle physics explored with ALICE at the LHC. First, the inelastic hadronic cross section of Helium-3, previously measured within a limited momentum range in fixed-target experiments, is investigated. Expanding this range up to 10 GeV/c, using data from ALICE, provides critical insights into light nuclei interactions and benchmarks theoretical models. Complementary measurements of deuterons serve as validation for the applied methodology, leveraging the advanced capabilities introduced in the LHC Run 3 campaign. Second, the production of light (anti)nuclei in high-energy hadronic collisions is examined. These measurements are instrumental in understanding the astrophysical sources of antinuclei and evaluating theoretical production mechanisms, which remain a topic of scientific debate. By comparing new data from Pb*Pb collisions at √sNN = 5.36 TeV from Run 3 with results from Run 2, this contribution provides a comprehensive analysis of (anti)nuclei production up to A=3. These advancements offer enhanced precision and scope, significantly contributing to the interpretation of antinuclei observations in astrophysical and experimental contexts.
