Neutron stars provide a unique laboratory for probing the properties of dense nuclear matter under extreme conditions of density. Understanding their internal structure requires a description of the Equation of State of matter at very high densities, which remains one of the main challenges in modern nuclear physics and astrophysics.
A Chiral Effective Field Theory approach can quite...
The nuclear equation of state (EoS) governs the structure of neutron stars and can be constrained by linking information from astrophysical observations, ab initio nuclear theory, and heavy-ion collisions within a Bayesian framework. In this work, we extend a unified meta-modeling approach to the EoS by implementing low-density corrections informed by energy density functionals calibrated to...
More and more data on correlation functions between hadrons as they can be measured in heavy-ion collisions using the femtoscopy technique [1,2] have recently become available. This applies not only to the nucleon-nucleon system but also to the hyperon-nucleon system. Thereby, they might help in the future to constrain hyperon-nucleon interactions.
As a first step in this direction, it is...
