| Outline of Final Research Achievements |
Nuclear force, which is the source of the atomic nucleus, is a very complex force that involves quarks, which are the constituent elements of nucleons. In particular, the reason why large repulsive forces occur at close distances where nucleons overlap is still unknown, and it has been pointed out that quarks play an important role. Therefore, it is expected that by investigating the force acting between protons and hyperons containing strange quarks, we will be able to clarify the role of quarks in the nuclear force. We succeeded for the first time in the world in measuring the angular distribution of their sigma particles and proton scattering with high precision by producing a lot of Σ hyperons. In particular, we were the first in the world to derive the strength of the Pauli repulsion between quarks from the differential cross section between Σ+ and protons.
