Light (anti-)nuclei production in Pb-Pb collisions at √sNN = 5.02 TeV measured with ALICE — •Malavika Panikkassery Salvan for the ALICE collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt — Technische Universität Darmstadt
The production mechanism of light (anti-)nuclei in heavy-ion collisions is not yet fully understood and is under debate in the scientific community. Two prominent phenomenological models typically used to describe the experimental data are: the statistical hadronization model (SHM) which assumes that all hadrons are emitted from a thermal source in local thermal and hadrochemical equilibrium, and the coalescence model where the baryons close to each other in phase space form a nucleus at the kinetic freeze-out.
The ratio of integrated yields of (anti-)deuterons to (anti-)protons in heavy-ion collisions is sensitive to the production mechanism as the two models predict different trends.
In this contribution, the deuteron-to-proton yield ratio measured in central (0-10%) Pb-Pb collisions at √sNN= 5.02 TeV with ALICE is presented and the results are discussed in the context of the two phenomenological models.
