Description
The study of (anti)nuclei production in hadronic collisions has proven to be a powerful tool to investigate the formation mechanism of loosely bound states. The $^{3}_{\Lambda}\text{H}$ is a bound state of Λ, proton, and neutron characterised by a Λ separation energy of few keV, which leads to a large wave function. As a consequence, the measured (anti-)$^{3}_{\Lambda}\text{H}$ production yields in pp and p-Pb collisions can resolve the difference between the Statistical Hadronisation Model (SHM) predictions, which are insensitive to the $^{3}_{\Lambda}\text{H}$ structure, and the coalescence model.
In this talk the first measurements of the production of (anti-)$^{3}_{\Lambda}\text{H}$ in pp and p-Pb collisions are presented. In this context, the measurements are compared with the expectations of coalescence and SHM. With the precision of the presented measurements, ALICE is setting tighter constraints to available theoretical models, in particular excluding some configurations of the Statistical Hadronisation and Coalescence models.
