Abstract:

Antinuclei can be produced in space either by collisions of high-energy cosmic rays with the interstellar medium or from the annihilation of dark matter particles decaying into standard model particles. High-energy hadronic collisions at accelerators create a suitable environment for studying the production and inelastic hadronic cross section of light (anti)nuclei. This information is essential to study the different sources of antinuclei coming from outer space in order to interpret future measurements.
This talk will present ongoing measurements with ALICE of the production of (anti)proton, (anti)deuteron & (anti)³He in Run3 using Pb-Pb collisions at SNN  = 5.36 TeV, as well as measurements of the hadronic inelastic cross section of (anti)proton & (anti)deuteron in pp collisions at S = 13.6 TeV. The inelastic cross section measurements aim to improve on the statistical uncertainty of similar studies done in Run2 and extend the study to matter (proton & deuteron) not yet measured with ALICE.
