Latest Results on (Anti-)Hypernuclei Production at the LHC with ALICE

Heavy-ion collision experiments offer a unique opportunity to study the production of (anti-) hyperon bound systems, called (anti-)hypernuclei. ALICE at the LHC measured the production of (anti-)hypertritons analyzing data collected in Pb–Pb collisions at the two center-of-mass energies of $\sqrt {{{s}_{{NN}}}} $ = 2.76 and 5.02 TeV. The analysis is performed by exploiting the excellent particle identification performance of the ALICE detector, in particular the energy loss of charged tracks in the Time Projection Chamber. In addition, the Inner Tracking System was used to separate the (anti-)hypertriton’s weak decay products from primary tracks through the precise determination of secondary vertices. Results on the (anti-)hypertriton lifetime measurement are discussed and compared to model predictions. The hypertriton yields are discussed and compared to the predictions of the statistical hadronization model. Plans for the future LHC Runs 3 and 4, scheduled to start in 2022, with improvements in statistics and spatial precision are also presented.
