Description
In accelerator experiments, the production of light (anti)nuclei such as (anti)deuterons
and (anti)Helium can be studied in a wide range of collision systems from small
(pp) to large (A–A) emission source sizes. However, the microscopic mecha-
nism by which they are produced and how they survive such hot and turbulent
conditions is still unknown. The most commonly used models to describe this
process are the statistical hadronization model and the coalescence approach.
In this talk, a state-of-the-art coalescence model based on the Wigner func-
tion formalism to describe (anti)nuclear production on an event-by-event basis
is presented. Additionally, this model is parameter-free and tuned on experi-
mental measurements of nucleon production spectra and of the emitting source
size. Such a model would find application in astroparticle physics to predict
(anti)nuclear fluxes in cosmic rays, which are a crucial ingredient for indirect
Dark Matter searches.
