Chiral effective field theory for hyperon-nucleon interactions — •Stefan Petschauer1, Johann Haidenbauer2, Norbert Kaiser1, Ulf-G. Meißner2, and Wolfram Weise11Physik-Department, Technische Universität München, D-85747 Garching, Germany — 2Institute for Advanced Simulation, Forschungszentrum Jülich, D-52425 Jülich, Germany

We calculate hyperon-nucleon interactions within the framework of chiral effective field theory. The irreducible potentials in momentum space are derived from the chiral SU(3) Lagrangian and include contributions from one- and two-meson exchange as well as contact terms up to next-to-leading order. Effects from intermediate decuplet baryons are considered as well. With these chiral baryon-baryon potentials a systematic study of hyperon-nucleon scattering and light hypernuclei is possible. Calculations for hyperon-nucleon cross sections have been performed using a regularized Lippmann-Schwinger equation and a good description of all the available data is achieved.
