Description
One of the challenges in nuclear physics is to describe finite nuclei and neutron stars within the same theoretical framework. A crucial entity is the nuclear Equation of State (EoS), which can be defined in terms of a set of empirical parameters (saturation density, compressibility, symmetry energy and its derivatives etc). In turn, these quantities are constrained using experimental data on ground state nuclear properties. The phenomenological models that are extensively employed in nuclear calculations have parameters that are fit to well-determined empirical nuclear observables, which must be updated with the rapidly improving experimental data. Further, they may contain spurious correlations with the empirical quantities. In this work, we develop a model-independent unified description of nuclear matter, that can be related directly to empirical quantities specifically sensitive to the EoS. We then apply this model to predict experimental observables such as charge radii and the neutron skin.
