Investigating the system size dependence of hypernuclei production with A < 5 using the ALICE detector
The production of (anti)hypernuclei is among the most promising probes for studying the production mechanism of light nuclei in high-energy hadronic collisions. According to coalescence predictions, the production of 3ΛH, 4ΛH, and 4ΛHe is sensitive to their internal wave function. In contrast, the y...

| Summary: | The production of (anti)hypernuclei is among the most promising probes for studying the production mechanism of light nuclei in high-energy hadronic collisions. According to coalescence predictions, the production of 3ΛH, 4ΛH, and 4ΛHe is sensitive to their internal wave function. In contrast, the yields predicted with the Statistical Hadronitazion Models (SHM) are based on the mass of the (hyper)nuclei and the freeze-out temperature, with no explicit dependence on the nuclear structure. In these proceedings, the measurements of 3ΛH, 4ΛH, and 4ΛHe from pp to central Pb–Pb collisions are presented. The results are based on the data samples collected by ALICE during the LHC Run 2 and Run 3. For the 3ΛH, in addition, an innovative method to extract its properties based on the system size dependency of its production yield is also presented. |
