Addressing the hypertriton lifetime puzzle with ALICE at the LHC

The ALICE Collaboration collected a large data sample of Pb-Pb collisions at sNN=5.02TeV 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, HΛ3 ,...

description The ALICE Collaboration collected a large data sample of Pb-Pb collisions at sNN=5.02TeV 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, HΛ3 , which is a bound state of a proton, a neutron and a Λ, is the lightest known hypernucleus. The results on the HΛ3 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 HΛ3 lifetime.

In particular, the (anti-)hypertriton, $^3_{\Lambda}$H, which is a bound state of a proton, a neutron and a $\Lambda$, is the lightest known hypernucleus. The results on the $^3_{\Lambda}$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 $^3_{\Lambda}$H lifetime.arXiv:1812.05832oai:cds.cern.ch:26533762018-12-14
