“…To determine the hypertriton mean lifetime, the ( 3 Λ H + 3 Λ H) sample was divided into four intervals in ct = MLc/p, where M is the hypernucleus mass, fixed to the reference value available from the literature M = 2.991 GeV/c 2 [12], L the decay length, c the speed of light, and p the total momentum. The signal was extracted in the intervals 1 ≤ ct <4 cm, 4 ≤ ct < 7 cm, 7 ≤ ct < 10 cm and 10 ≤ ct < 28 cm, and was corrected by the detector acceptance, the reconstruction efficiency and the absorption of 3 Λ H ( 3 Λ H) in the material.…”

In high-energy heavy-ion collisions nuclei and hypernuclei emerge from the hot and dense fireball formed in the reaction region. Thanks to its excellent particle identification and momentum measurement performance, the ALICE detector allows for the identification of deuterons, tritons, 3 He and 4 He and the corresponding anti-nuclei. This is achieved via the measurement of their specific energy loss in the Time Projection Chamber and the velocity measurement by the Time-Of-Flight detector. Moreover, thanks to the Inner Tracking System capability to separate primary from secondary vertices, it is possible to identify (anti-)hypertriton through the mesonic weak decay 3 Λ H → ( 3 He + π − ). The direct decay time measurement of (anti-)hypertriton is difficult, but the excellent determination of primary and decay vertices, i.e. of the decay length, allows for the measurement of mean lifetime via an exponential fit of the proper decay time distribution. Results on the measurement of the hypertriton mean lifetime will be shown. Plans for the future LHC Run2 and Run3, with the expected improvements in the statistics and precision, will also be presented.

“…Motivation of our current work is to study CSB with A=4 mirror  hypernuclei. Since 1960s, emulsion experiments reported B  of 4  H and 4  He in ground state (0 + ) [1][2][3]. The combined results for B  (0 + ) of 4  H and 4  He were reported by M. Juric et al [4] to be 2.04 ± 0.04 MeV and 2.39 ± 0.03 MeV, respectively.…”

This combined data gave a large binding energy difference between 4  H and 4  He, B  (0 + ) = 0.35 ± 0.05 MeV and thus CSB effect appears significantly.…”
