Neutron skin systematics from microscopic equations of state

TL;DR

This paper analyzes neutron skin thicknesses using microscopic equations of state derived from chiral nuclear forces, comparing predictions with recent experimental constraints to improve understanding of nuclear structure.

Contribution

It introduces a comprehensive analysis of neutron skins based on microscopic chiral interactions, integrating recent experimental data for validation.

Findings

Microscopic equations of state predict neutron skin thicknesses consistent with experimental constraints.

Chiral two- and three-nucleon forces at N3LO provide reliable predictions for neutron-rich nuclei.

Comparison with PREX II and other measurements enhances understanding of nuclear matter properties.

Abstract

This paper presents an analysis of neutron skins based on fully microscopic equations of state, including chiral two- and three-nucleon forces consistently at N3LO. Other theoretical predictions and recent constraints are also addressed, such as those from the PREX II experiment and the latest parity-violating electron scattering measurement of the 27Al neutron skin.
