The Sendai triton calculation with three-nucleon potentials

Where can we see the effects of quarks remains a fundamental question in nuclear theory physics. A bold approach is to try to reproduce physical quantities theoretically by utilizing a quark picture with imagination. A conservative but safer approach may be to study the triton as thoroughly as possible using realistic two- and three-nucleon potentials. We are taking the latter approach. In fact, our calculation of the EMC effect, which was one thought to be a realization of the quark-gluon picture of nuclei, suggests that we might not have to make recourse to this picture. The calculation was done for 3He, while experimental data for 4He are shown. We hope that an experiment for 3He is done soon, to check whether our conservative approach actually works for the EMC effect. (orig./WL)
