Description

Hypernuclei are bound states formed between nucleons and hyperons. The measurement of their production in high-energy hadronic collisions provides a powerful probe for investigating the interaction forces that bind strange baryons to ordinary nucleons and for testing nucleosynthesis models. Among the light hypernuclei, the possible existance of the $\Lambda$-n-n remains an open question. After the first claim of observation in 2013, no other experimental evidence has been presented supporting its existence, whereas state-of-the-art model calculations do not expect it to be bound. This contribution presents the search for the $\Lambda$-n-n bound system in Pb-Pb collisions collected by ALICE during LHC Run 3 and discuss its consequences in the overall picture of hypernuclei production at the LHC.
