31. The European Networking Activity THEIA: achievements and prospects

Josef Pochodzalla (University Mainz)

09/10/2023, 10:00

The cooperation of world-leading experimentalists and theoreticians in the field of strangeness nuclear physics with experts of the neutron star community is the aim of the networking activity THEIA. The main objectives of THEIA were
• the hypertriton puzzle and its implication for fragment formation in heavy ion reactions.
• the study of antihyperons in nuclei by antiproton nucleus...

24. Application of SMS chiral interactions to light hypernuclei

Andreas Nogga (IAS-4, Forschungszentrum Juelich)

09/10/2023, 10:45

Recently, a new generation of chiral hyperon-nucleon interaction has been developed [1]. In this
contribution, I will discuss the properties of these interactions and apply them to light hypernuclei.
A special focus will be put on using different chiral orders to obtain reliable uncertainty estimates [2].

22. Light hypernuclei in the frameworkd of J-NCSM and $\chi$ EFT

Hoai Le

We study s- and light p-shell $\Lambda$ hypernuclei from a microscopic level based on the ab initio Jacobi no-core shell model (J-NCSM) in combinations with
baryon-baryon interactions derived in the frame work of chiral effective field theory. The employed potentials are softened with similarity renormalization group evolution in order to speed up the convergence of the NCSM calculations. We...

23. Dense nuclear matter with phenomenological short distance repulsion

Jesper Leong (University of Adelaide)

09/10/2023, 12:45

The possibility of short distance repulsion applicable inside the cores of neutron stars is incorporated into the hadron equation of state generated by the quark-meson coupling model. Whilst obtaining an incompressibility compatible with data on giant monopole resonance, neutron stars are predicted to have a maximum mass in excess of 2.1 $M_\odot$, even when hyperons are included under...
