Protons and Light Nuclei from Au+Au Collisions at √sNN = 2.4 GeV measured with HADES — •Melanie Szala for the HADES collaboration — Goethe-Universität, Frankfurt am Main, Germany
The HADES experiment at the SIS18 accelerator of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt measured Au+Au collisions at 1.23A GeV.
In this energy regime protons make up the bulk of the produced particles, yet a large fraction of them (≈40%) are bound in light nuclei.
With the goal to unterstand the created system in heavy-ion collisions in this energy regime and the production mechanism of these nuclei, we present the results of p, d, t and 3He.
The production of nuclei in heavy ion collisions is commonly discussed within two different scenarios: the thermal-statistical hadronization models and the coalescence model. We will compare our data to state of the art models and compare the results to those in heavy-ion collisions at higher energies.
