We use SU(3) chiral effective field theory to describe the two- and three-baryon forces. Results for the hyperon-nucleon interaction at next-to-leading order are reported. These potentials include one- and two-meson exchange diagrams as well as contact terms with SU(3) symmetric low-energy constants. Furthermore we present potentials for the leading order three-baryon interactions, which...

I review recent progress in the application of chiral effective field theory
to nuclear forces and low-energy nuclear observables. Both the continuum
and the lattice formulations will be addressed.

One of the interesting subjects in hadron physics is to look for the multiquark configurations. One of candidates is the H-dibaryon (udsuds), and the possibility of the bound H-dibaryon has been recently studied from lattice QCD.
We also extend the HAL QCD method to define potential on the lattice between baryons to meson-meson systems including charm quarks to search for the bound tetraquark...

The behavior of the $\phi$ meson at finite density is studied, making use of a QCD sum rule approach in combination with the maximum entropy method. It is demonstrated that a
possible mass shift of the $\phi$ in nuclear matter is strongly correlated to the strangeness content of the nucleon, which is proportional to the strange sigma term, $\sigma_{sN}$. In contrast to earlier studies, our...

The hyperon-pion and hyperon-nucleon(s) correlations following K- nuclear absorption in Helium and Carbon were investigated with the KLOE drift chamber and the results will be presented. To this end, KLOE [1] data (from 2004-2005) was analyzed using the detector itself as an active target. Also results from a more recent run (end of 2012) with a dedicated solid Carbon target will be...
