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." }
