By October 22, RIKEN Cluster for Pioneering Research, iTHEMS and Institute for Cosmic Ray Research concluded a research collaboration agreement to further promote research cooperation in the field of multi-messenger cosmic ray physics, including joint research and personnel exchanges.

-Building a New Innovation Platform through Collaboration between Academia and Business-

RIKEN, RIKEN Innovation Co., Ltd. and JSOL Corporation have jointly established RIKEN SUURI CORPORATION, effective October 1, 2020. This is RIKEN's first investment in a venture. RIKEN, Japan's only research institute for the natural sciences, has a wealth of research and development capabilities that have been cultivated over its more than 100-year history, the first product to be brought to the market by RIKEN's investment was neither state-of-the-art equipment nor a drug, but "the best brains in the mathematical sciences itself". RIKEN SUURI CORPORATION aims to be a company that maximizes the use of mathematical sciences to solve the fundamental problems of society.

On October 22, the iTHEMS-phys seminar entitled "Realistic shell model and chiral three-body force” given by Dr. Tokuro Fukui (YITP, Kyoto U.) was held.

He and his collaborators proposed the way to calculate matrix elements of the three-body nuclear force, and showed the importance and effects of the three-body nuclear force in medium-heavy nuclei, such as calcium and nickel isotopes, starting from the chiral nuclear force using the shell model calculation. During his seminar, he introduced their works from the introduction to state-of-art results.

The seminar was held via the Zoom online conference systems, and more than 25 people including outside of iTHEMS attended the seminar.
