Studying (anti)nuclei formation in heavy ions using an advanced coalescence model — •David Casado — Technical University Munich

Coalescence is a major model used to describe the formation of light (anti)nuclei in high energy collisions. It is based on the assumption that two nucleons close in phase-space can coalesce and form a nucleus. Antideuteron and antihelium nuclei have been proposed as a detection channel for dark matter annihilations and decays in the Milky Way, due to the low astrophysical background expected. In order to correctly interpret any future antinuclei measurement in space, the production of antinuclei has to be well understood. In this presentation a more advanced approach is employed combining event-by-event Monte Carlo simulations with a microscopic coalescence picture based on the Wigner function formalism. The antiproton production in the event generator EPOS 3 is compared to measurements from the STAR Collaboration.
