Mansour three body force applied to nuclear matter

TL;DR

This paper introduces a density-dependent two-body potential as a correction to the Brueckner-Hartree-Fock (BHF) potential, aiming to improve nuclear matter saturation predictions aligning with experimental data.

Contribution

It presents a novel correction method using a two-body density-dependent potential to simulate three-body forces in nuclear matter calculations.

Findings

New saturation curves match experimental results

Energy per particle curves are computed for various nuclear matter types

The method improves the accuracy of nuclear matter models

Abstract

In the present work we are going to add a correction to the BHF potential calculation by introducing a two- body density dependent potential that acts as a three body interaction. Adding the result of this potential to the BHF potential would give us new saturation curves which coincide with the results obtained from the experiment. We compute the energy per particle versus density curves for symmetric nuclear matter, pure neutron matter and the symmetry energy using modern nucleon nucleon potentials like CD Bonn.
