Predicting the Lambda binding energy in nuclear matter

Abstract

The purpose of this note is to report predictions of the binding energy of the $\Lambda$ hyperon in nuclear matter using the latest version of the Juelich nucleon-nucleon meson-exchange potential. Results from a conventional Brueckner calculation are compared with previously reported values. A calculation including Dirac effects on the $\Lambda$ single-particle potential is also presented. Issues encountered in Dirac calculations with nucleon-hyperon potentials are discussed.
