Hypernuclei production in Pb–Pb collisions at sNN=2.76 TeV with ALICE at the LHC

Abstract

Abstract Results on (anti)hypertriton production in Pb–Pb collisions at s NN = 2.76 TeV are reported using the data samples collected by the ALICE experiment during the LHC heavy-ion runs at the end of 2011. The (anti) H Λ 3 signal is extracted from the study of its mesonic decay ( H Λ 3 → He 3 + π − ) via the topological identification of secondary vertices. The ( He 3 / He ¯ 3 , π ) invariant mass distributions in different transverse momentum intervals are shown.
