Outline of Final Research Achievements

The main aim of this project is to investigate the existence of charm-hyperuclei as a bound state, which is composed of charm baryon and nuclei　and to construct the interaction between charm baryon and nucleon by the study of structure of charm-hypernuclei. For this purpose, we constructed charm baryon-nucleon interaction from view point of one-boson exchange model. The constructed interaction is included ΛcN-ΣcN-Σc*N coupling. With the use of this interaction, we pointed out to have a bound state with A=4 charm hypernucleus by solving a couple channel calculation of NNNΛc-NNNΣc four-body problem.
