Hyperon-Nuclear Interactions From SU(3) Chiral Effective Field Theory Open

S. Petschauer, J. Haidenbauer, Norbert Kaiser, Ulf-G. Meißner, Wolfram Weise · 2020

Physics Mathematics

The interaction between hyperons and nucleons has a wide range of\napplications in strangeness nuclear physics and is a topic of continuing great\ninterest. These interactions are not only important for hyperon-nucleon\nscattering but also…

Leading three-baryon forces from SU(3) chiral effective field theory Open

S. Petschauer, Norbert Kaiser, J. Haidenbauer, Ulf-G. Meißner, W. Weise · 2016

Physics Philosophy

Leading three-baryon forces are derived within SU(3) chiral effective field\ntheory. Three classes of irreducible diagrams contribute: three-baryon contact\nterms, one-meson exchange and two-meson exchange diagrams. We provide the\nminimal…

Baryonic forces and hyperons in nuclear matter from SU(3) chiral effective field theory Open

S. Petschauer · 2016

Physics

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 …
