Production of deuterons in pp collisions at √s = 13 TeV with ALICE at the LHC — •Benedikt Krimphoff for the ALICE collaboration — Goethe-Universität, Institut für Kernphysik, Frankfurt am Main

The production of nuclei in high-energy collisions is commonly discussed within two different scenarios: the thermal-statistical model and the coalescence model. Both approaches are successful in describing the data when applied with certain parameters but they might exhibit more dependencies when used for a wider range of energies.
With the measurement of (anti-)deuterons in √s=13 TeV pp collisions we want to shed light on the nature of light nuclei and their production mechanisms. In particular, the measurement of the production cross section at an unprecedented collision energy may reveal important constraints for the models.
In this presentation we describe the procedure to extract a deuteron spectrum and present the current status of the analysis.
