Brief Summary of Each Supplement


Progress of Theoretical Physics Supplement No. 185



Hypernuclei and Baryon-Baryon Interaction


Ed. by E. Hiyama, T. Motoba and Y. Yamamoto

This volume of the Supplement is to review recent progress of hypernuclear physics from viewpoints of theory and experiment.

Systematic studies of hypernuclear physics in Japan began in the context of the research project Cluster Structure of Hypernuclei in the 1980s. The results obtained during these years are summarized in Prog. Theor. Phys. Suppl. No. 81 (1985). After 1985, further developments in hypernuclear physics have been achieved extensively. Then, those results are summarized in Prog. Theor. Phys. Suppl. No. 117 (1994). In the 1990s, the next generation meson-theoretical models of hyperon-nucleon (YN) and hyperon-hypreon (YY) interactions were constructed by the Nijmegen group. Furthermore, new techniques for accurate few-body calculations have been developed and have been applied to various hypernuclear systems systematically.

Experimentally, many epoch-making data regarding hypernuclear physics have been obtained, for example, high-resolution γ-ray data for Λ hypernuclei and the uniquely identified double-Λ hypernuclei in emulsion.

In this volume, we focus on elucidating three points: (1) the new understanding we have come to obtain; (2) the important issues still remaining; and (3) the kinds of experiments that should be carried out at J-PARC.
