Hyperon Interaction in Free Space and Nuclear Matter — •Madhumita Dhar1 and Horst Lenske1,2 — 1Justus-Liebig University Giessen — 2GSI, Darmstadt
A new approach to the SU(3) flavour symmetric meson-exchange model is introduced to describe free space baryon-baryon interaction. The Bethe-Salpeter equations are solved in a 3-D reduction scheme. The coupling of the various channels of total strangeness S and conserved total charge Q is studied in detail. Special attention is paid to the physical thresholds. The derived vacuum interaction has then been used to derive nuclear medium effect by employing the Pauli projector operator in 3-D reduced Bethe-Salpeter equation.The in-medium properties of the interaction are clearly seen in the variation of the in-medium low-energy parameters as a function of density.
