Correlations in exotic nuclear matter — •Patrick Konrad and Horst Lenske — Institut für Theoretische Physik, Universität Giessen, Germany

We investigate short range correlations in asymmetric nuclear and hypernuclear matter. Self-energies due to short range correlations and their influence on the nucleon and Λ-hyperon spectral functions are described in an approach accounting for a realistic treatment of mean-field dynamics by a phenomenological Skyrme energy density functional. Landau-Migdal theory is used to derived the short range interaction from the Skyrme energy density functional, especially investigating short-range dynamics by subtracting the long range pionic contributions to the nucleonic spectral functions. The sensitivity of correlations on the parameters of underlying Skyrme energy density functional is discussed. Results on self-energies and spectral functions in asymmetric nuclear matter, hypermatter and β-stable (Λ,n,p,e)-neutron star matter are presented.
