Production of hypernuclei in Pb-Pb collisions at $\sqrt {s_{NN}} = 2.76$ TeV with ALICE at the LHC

Results on (anti-)hypertriton production in Pb-Pb collisions at = 2.76 TeV, obtained by ALICE at the LHC, are reported. The (anti-)3Λ H signal is extracted exploiting its mesonic decay (3ΛH → 3He + π), via the topological identification of secondary vertices and the analysis of the invariant mass di...

description Results on (anti-)hypertriton production in Pb-Pb collisions at = 2.76 TeV, obtained by ALICE at the LHC, are reported. The (anti-)3Λ H signal is extracted exploiting its mesonic decay (3ΛH → 3He + π), via the topological identification of secondary vertices and the analysis of the invariant mass distributions of (3He, π) pairs. The (3He,π) invariant mass distributions in different transverse momentum and in proper time intervals are shown. Search for ΛΛ state (H-Dibaryon) via its decay H-Dibaryon → Λpπ− is discussed. As no H-Dibaryon signal is observed, an upper limit on its production yield has been determined.
