Identification and prospects for light (anti)nuclei measurements with the upgraded ALICE detector at the LHC Run 3.

The ALICE detector at the CERN LHC is particularly suited to study light (anti)nuclei such as (anti)deuterons, (anti)tritons and (anti)$^{3}He$ produced in high-energy hadronic collisions. Their production mechanism is investigated by comparing experimental data with phenomenological models such as the SHM and coalescence. The coalescence mechanism also has several applications in cosmic-ray antinuclei studies and indirect dark-matter searches. The ALICE apparatus underwent a series of major upgrades during the LHC long shutdown 2 to take advantage of the luminosity increase. We will present particle identification performance for light (anti)nuclei studies and prospects for precision measurement of $A=3$ and $A=4$ nuclei and antinuclei in proton-proton and heavy-ion collisions that will be enabled by the unprecedented integrated luminosities expected in Run 3.
