Self-consistent single-nucleon and single-Lambda potentials in strange nuclear matter with the Dirac-Brueckner-Hartree-Fock approach

TL;DR

This paper uses the Dirac-Brueckner-Hartree-Fock approach to calculate self-consistent single-particle potentials for nucleons and Lambda hyperons in strange nuclear matter, considering relativistic effects and various conditions.

Contribution

It introduces a self-consistent calculation of nucleon and Lambda potentials in hyperonic matter using a relativistic framework, accounting for Lambda concentration and momentum dependence.

Findings

Relativistic Dirac effects significantly influence Lambda binding energies.

Potentials depend on momentum, density, and Lambda fraction.

The approach provides detailed insights into hyperonic matter properties.

Abstract

We calculate self-consistent single-nucleon and single-Lambda potentials in hyperonic matter for different Lambda concentrations. The predictions include relativistic Dirac effects as reported previously in a calculation of the Lambda binding energy in symmetric nuclear matter. We discuss the dependence on momentum, density, and Lambda fraction.
