Production of (anti-)t, (anti-)3He and (anti-)4He at √sNN=5.02 TeV with ALICE at the LHC — •Esther Bartsch for the ALICE collaboration — Institut für Kernphysik, Goethe-Universität Frankfurt
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 √sNN=5.02 TeV will be 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.
