Abstract

In these proceedings, the search for 4Li̅ in Pb-Pb collisions with ALICE is presented. The particle is reconstructed via its two-body decay channel 4Li̅ → p̅ + 3He̅, using femtoscopic correlations. A dedicated analysis procedure has been developed to subtract the correlated and uncorrelated p̅ + 3He̅ combinatorial background. The production yield of 4Li̅ is compared with that of 4He̅. Owing to the presence of several 4Li resonances and their spin degeneracy, the production of 4Li̅ is expected to be enhanced with respect to the compact 4He̅, making this new measurement a sensitive probe for testing nucleosynthesis models in high-energy hadronic collisions.
