Quark Cluster Model of Baryon-Baryon Interactions


Edited by Makoto Oka, Kiyotaka Shimizu and Koichi Yazaki

This volume contains review articles summarizing the works on the quark model for baryons and their interactions that have been carried out by the Tokyo group over the past two decades. The origin of nuclear force, which is the most fundamental ingredient of nuclear dynamics, has been a central problem of nuclear physics for long time. The strong short-range repulsion, especially, is expected to reflect the substructures of nucleons. A theoretical framework in which the quark substructure of nucleon is explicitly taken into account to compute the short-range nuclear force is the quark cluster model. The theoretical nuclear physics group of University of Tokyo formulated the model in 1979, named it and developed the model from various viewpoints over the past two decades.

This volume contains the reviews as well as the discussions of recent topics such as the relation of the quark confinement potential to lattice QCD calculations, effects of the instanton induced interactions, the hyperon-nucleon and hyperon-hyperon interactions, the weak decay of hyperons in nuclei, and the H-Dibaryon.
