Outline of Final Research Achievements

Purpose of this research is revealing whether hyperon superfluidity is realized in the core of neutron stars. Since hyperon interactions are experimentally unknown, first we determine them based on the fundamental theory QCD, and then apply them. In order to study hyperon superfluidity, hyperon single-particle potential is an indispensable quantity.
Within this budget period, I could derive hyperon interaction by doing lattice QCD numerical calculation, and could compute hyperon single-particle potential applying obtained interactions to the Brueckner-Hartree-Fock quantum many-body theory. Depth of the obtained hyperon single-particle potentials qualitatively agree well with the hypernuclear experimental data. This is the first ever success of explaining hypernuclear physics from the fundamental theory QCD, and it is highly appreciated.
