Hypertriton production in Pb–Pb collisions with ALICE at the LHC — •Lukas Kreis for the ALICE collaboration — Research Division and ExtreMe Matter Institute EMMI, GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt — Institut für Kernphysik, Technische Universität Darmstadt
The ALICE experiment at the CERN LHC is devoted to the study of nucleus–nucleus collisions at the highest energies ever reached in the laboratory. The excellent particle identification allows to discern particles in a wide range of mass. The secondary vertices can be reconstructed within the Inner Tracking System. These capabilities enable the study of light hypernuclei in heavy-ion collisions. In this talk the ongoing investigation of hypertriton and anti-hypertriton production in Pb–Pb collisions at √sNN = 5.02 TeV is presented, following the previous analysis at √sNN = 2.76 TeV. The decay products are identified based on their specific energy loss in the Time Projection Chamber. The Λ3 H and Λ3 H are reconstructed using the invariant mass of 3He and π− and 3He and π+, respectively.
