Ito International Research Center (IIRC) symposium
"Perspectives of the physics of nuclear structure"

November 1-4, 2017
Ito hall (Nov. 1-2), Koshiba hall (Nov. 3-4)
The University of Tokyo, Hongo, Tokyo, Japan

The international symposium "Perspectives of the physics of nuclear structure" will be held from November 1st to 4th, 2017, at the Ito Hall and Koshiba Hall, Hongo campus, the University of Tokyo.
The physics of nuclear structure presents a notable progress in recent decades through the exploration and the understanding of new features in nuclear structure, including "neutron halo" and "island of inversion" as well as more recent development such as "shell evolution", "ab initio approaches", etc. These are obviously due to developments, experimental as well as theoretical, on and with rare isotopes or exotic nuclei. Its interdisciplinary applications are also developing.
This symposium will be devoted to discussing such recent achievements and further perspectives in the physics of nuclear structure, with a slight emphasis on the developments of the shell model in the past and future. The utilization of high-performance computing will be discussed. The scientific program is composed of invited and contributed talks and poster session.

The subjects to be covered in this symposium include
1. Exotic structure of neutron- and proton-rich nuclei and shell evolution
2. New facets of nuclear forces and effective interactions in nuclei
3. Shape evolution, shape coexistence and quantum phase transition
4. Ab initio approaches to nuclear structure
5. Shell model in the next decade
6. Nuclear excitations and reactions a la shell model
7. Applications to astrophysics, particle physics and nuclear engineering
8. Advancement in large-scale many-body calculations

Title: Nuclear force from QCD on lattice and its application
Date: February 8, 2017 (Wed) 16:00 - 17:00
Place: Room 907, Faculty of Science Building 1, Hongo, Univ. Tokyo

Explaining or predicting properties of nuclei starting from QCD is one of the most challenging problems in physics. There are several attempts to extract ground state energy of nuclei in lattice QCD simulations, however it turned out that direct extraction is practically impossible due to small energy splittings between states. We adopt an alternative approach to study nuclei starting from QCD. Our strategy consists of two stages. First, we extract two-nucleon interaction from QCD by means of the HAL QCD method. Namely, we carry out lattice QCD numerical simulation with six quarks, and measure the so called baryon four point correlation function, and construct potential of the baryon interaction through the equation which the function satisfy. Then, we apply the potential to modern methods for few-body system or established many-body theories for nuclei.

In order to derive general baryon-baryon interactions including nuclear force in the physical world, now we are performing lattice QCD simulation with almost physical quarks. However, we need more time to finish our calculation. Therefore, this time, we use NN potential from lattice QCD at unphysically large u and d quark mass, e.g. corresponding to a pseudo-scalar meson mass 469 MeV and a nucleon mass 1161 MeV. Obtained NN potentials posses common features of phenomenological ones, although their strength are weaker than reality. Namely, they have strong repulsion at short distance, attraction at medium and long distance, and strong tensor force. Accordingly, the potentials reproduce experimental data of NN scattering qualitatively. With these NN potentials in the unphysical hadron worlds, we study doubly closed nuclei 4He, 16O, and 40Ca, and infinite matter. We find that these nuclei are bound at pseudo-scalar meson mass 469 MeV.
