Production of (anti-)t, (anti-)³He and (anti-)⁴He at √(s_NN) = 5.02 TeV with ALICE at the LHC

The high collision energies reached at the LHC lead to significant production yields of light (anti-)nuclei in proton-proton and, in particular, Pb-Pb collisions. The excellent particle identification capabilities of the Time Projection Chamber, using the specific energy loss (dE/dx), and the time-of-flight measurement, allow for the detection of these rarely produced particles. Furthermore the Inner Tracking System gives the possibility to separate primary nuclei from those coming from the decay of heavier systems. New results on (anti-)tritons, (anti-)³He and (anti-)⁴He production in Pb-Pb collisions at √(s_NN) = 5.02 TeV are presented. The goal is to study production mechanisms such as coalescence and thermal models, and to compare them to those in heavy-ion collisions at lower energies.
