| Outline of Final Research Achievements |
We consider the new type of nuclei which contain charm or bottom flavor as multi-baryon systems with heavy quarks. Those are called “charm nuclei” or “bottom nuclei”. In this study, focusing on the “heavy quark (spin) symmetry” which is a characteristic symmetry for a heavy quark, we constructed the inter-hadron interaction between a heavy hadron and a nucleon as the heavy-hadron effective theory, and gave theoretical predictions about the properties of heavy hadrons in nuclear systems. We considered the heavy-light meson (a bound state of a heavy antiquark and a light quark) as one of the simplest systems, and investigated their masses and decays in nuclear systems by applying the obtained interaction to the many-body calculations.
