Bryon-baryon interaction has attracted much attention since lattice QCD calculation of nuclear force has become possible recently. The characteristics of the nuclear force, attractive potential of long and intermediate range and repulsive core at short distance, is reproduced from QCD. The baryon-baryon interaction in the flavored world from QCD has just started. J-PARC is now ready for the experimental studies.
Experimental studies of hyperon-nucleon and hyperon-hyperon interaction have been performed by spectroscopy of hypernuclei and hyperon-nucleon scatterings. In this talk, we briefly review the past experimental studies and discuss possible experiments especially at J-PARC. The possible study of charmed baryon-baryon interaction is also discussed.
