Production of hypernuclei at FAIR — •Theodoros Gaitanos, Alexei Larionov, and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen, Germany

The strangeness sector of the strong interaction is important for our knowledge on, e.g., nuclear astrophysics. It is still a widely debated topic of current research. Hypernuclear production in heavy-ion collisions and p-nucleus collisions offers the opportunity to investigate the hyperon-nucleon and hyperon-hyperon interaction inside a hadronic environment in terrestrial laboratories. We study the formation of fragments with and without strangeness contents in the framework of a dynamical transport model (Giessen Boltzmann-Uehling- Uhlenbeck, GiBUU) [ 1 ] and a statistical approach (Statistical Multifragmentation Model, SMM) of fragment formation [ 2 ]. We use a coalescence picture for the production of single-Λ and double-Λ hypernuclei, and provide theoretical estimates on their spectra and inclusive cross sections in heavy-ion collisions and p induced reactions, relevant for HypHI and PANDA experiments at FAIR.
