Dense Baryonic Matter and Strangeness in Neutron Stars

Understand

Recent developments of chiral effective field theory (ChEFT) applications to nuclear and neutron matter are summarized, with special emphasis on a (non-perturbative) extension using functional renormalisation group methods.

• Topics include: nuclear thermodynamics, extrapolations to dense baryonic matter and constraints from neutron star observables.
• Hyperon-nuclear interactions derived from SU(3) will be discussed with reference to the "hyperon puzzle" in neutron star matter.
