# EoS from terrestrial experiments: static and dynamic polarizations of nuclear density

## TL;DR

This paper critically analyzes the nuclear matter and neutron matter equations of state using terrestrial experimental data, focusing on parameters like incompression modulus and symmetry energy coefficients, to refine understanding of nuclear properties.

## Contribution

It provides a comprehensive re-evaluation of key EoS parameters using recent experimental results and theoretical models, improving the accuracy of nuclear matter descriptions.

## Key findings

- Revised nuclear incompression modulus $K_{ ext{infty}}$ based on RPA and experimental data.
- Updated symmetry energy coefficients $J$, $L$, and $K_{sym}$ from recent mass models and experiments.
- Enhanced understanding of nuclear density polarization effects.

## Abstract

We critically examine nuclear matter and neutron matter equation of state (EoS) parameters by using best available terrestrial experimental results. The nuclear incompression modulus $K_{\infty}$ is re-examined in comparisons with RPA results of modern relativistic and non-relativistic EDF and up-to-date experimental data of isoscalar giant monopole resonance energy of $^{208}$Pb. The symmetry energy expansion coefficients $J$, $L$ and $K_{sym}$ are examined by recent FRDM mass model and the neutron skin of $^{48}$Ca extracted from $(p,p')$ experiments.
