  The interaction between hyperons and nucleons has a wide range of
applications in strangeness nuclear physics and is a topic of continuing great
interest. These interactions are not only important for hyperon-nucleon
scattering but also essential as basic input to studies of hyperon-nuclear few-
and many-body systems including hypernuclei and neutron star matter. We review
the systematic derivation and construction of such baryonic forces from the
symmetries of quantum chromodynamics within non-relativistic SU(3) chiral
effective field theory. Several applications of the resulting potentials are
presented for topics of current interest in strangeness nuclear physics.
