Abstract

The ALICE Collaboration collected a large data sample of Pb-Pb collisions at root S-NN = 5.02 TeV in 2015 at the Large Hadron Collider (LHC) and the excellent particle identification (PID) capabilities allow for the detection of rarely produced (anti-)hypernuclei. In particular, the (anti-)hypertriton, H-3(Lambda), which is a bound state of a proton, a neutron and a A, is the lightest known hypernucleus. The results on the H-3(Lambda) production are compared with the predictions from a model based on coalescence approach and from statistical-thermal models to investigate the production mechanisms in heavy-ion collisions. Emphasis will also be put on the latest and more precise determination of the H-3(Lambda) lifetime.
