- Abstract:
- In this work the baryon-baryon interaction is studied at next-to-leading order in SU(3) chiral effective field theory and applied to hyperon-nucleon scattering. The properties of hyperons in isospin-symmetric as well as asymmetric nuclear matter are calculated within the Bruecker-Hartree-Fock formalism. Moreover, the leading three-baryon interaction is derived and its low-energy constants are estimated from decuplet intermediate states. We conclude, that chiral effective field theory is a well-s... »

- In dieser Arbeit untersuchen wir die Baryon-Baryon-Wechselwirkung in nächst-führender Ordnung in der SU(3) chiralen effektiven Feldtheorie und wenden diese auf die Hyperon-Nukleon-Streuung an. Es werden die Eigenschaften von Hyperonen in isospin-symmetrischer sowie asymmetrischer Kernmaterie mittels des Brueckner-Hartree-Fock-Formalismus berechnet. Schließlich wird die führende Drei-Baryon-Wechselwirkung abgeleitet und ihre Niedrigenergiekonstanten durch Beiträge von Dekuplettbaryonen in Zwische... »
