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

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.
