Addressing the hypertriton lifetime puzzle with ALICE at the LHC
arXiv:1812.05832 · doi:10.1016/j.nuclphysa.2018.11.016
Abstract
The ALICE Collaboration collected a large data sample of Pb-Pb collisions at = 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, which is a bound state of a proton, a neutron and a , is the lightest known hypernucleus. The results on the H 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 lifetime.
