Prof. Nakahama received the Silver Award of Toshiko Yuasa Prize in recognition of contribution to study of new physics using particle accelerators. The award ceremony was held online by Ochanomizu University on Monday, February 15, 2021.  I am very honoured to receive the Toshiko Yuasa award for international female researchers in physics. I greatly appreciate the continuous support of my colleagues in KMI, N-lab, the LHC-ATLAS experiment and my family. In the interdisciplinary & international research environments at KMI, I could …


The 3rd KMI School “Machine Learning in Particle and Astrophysics (KMI 2020)” was held on November 16-20, 2020, with about 60 participations from 12 countries. KMI School 2020 was originally scheduled for March 2020, but had to be postponed due to the COVID-19 pandemic. The five days of lectures and group works were conducted using online communication tools, allowing for fruitful discussions across borders. Due to the limited number of participants, we had to close the pre-registration for the group …


A group of researchers, including scientists from Nagoya University, the High Energy Accelerator Research Organization (KEK), the University of Tokyo, Kyoto University, Kyushu University, Osaka Electro-Communication University, Tsukuba University, and Osaka University, reported the first result of neutron lifetime measurement by adopting a new experimental technique. Neutrons are one of the particles that constitute the nuclei of atoms. Neutron decay is related to the mechanism of synthesis of elements in the early universe and particle physics. This result paves a …


The website of DMNet is launched at     The Japan Society for the Promotion of Science (JSPS) selected KMI’s proposal “International research network to reveal dark matter in the universe by multidisciplinary approach in particle and astrophysics” as one of the Core-to-Core programs.  The Core-to-Core program is designed to create top world-class research centers that partner over the long term with other core research institutions around the world in advancing research in leading-edge fields on issues of high international …


KMI had the International Advisory Board (IAB) Meeting online on Monday, December 14th, 2020.KMI has the IAB meeting every two years to report KMI’s activities and discuss our next step for the future of KMI.  This year, KMI welcomed two outstanding scientists as new members of the International Advisory Board: Prof. Hitoshi Murayama from University of California, Berkeley and Prof. Misao Sasaki from Kavli Institute for the Physics and Mathematics of the Universe, The University of Tokyo. We were able …

Dr. Tomohiro Abe from the Division of Theoretical Studies won the 15th Seitaro Nakamura Award of the year from the Particle Research Scholarship Foundation. The award named after Dr. Seitaro Nakamura (1913-2007), who had produced substantial researches on theoretical particle physics particularly on two-meson and beta decay, was established in 2006 in order to encourage young researchers for their future endeavors in particle physics and the related field. Awarded Paper: “The effect of the early kinetic decoupling in a fermionic …


New results from the Large Hadron Collider (LHC) experiments were announced in the press release by CERN on 3rd August followed by the press release by Nagoya University on 11th August. Nagoya University participates in the ATLAS experiment at LHC. M. Tomoto (Designated Professor, Graduate School of Science and KMI), Y. Horii (Lecturer, Graduate School of Science), Y. Kano (Research Fellow, Graduate School of Science), and T. Kawaguchi (Graduate Student, Graduate School of Science) contributed to this research. The ATLAS …


A group of researchers including scientists from Nagoya University, the J-PARC Center, Tokyo Institute of Technology, Osaka University, Kyushu University, and Japan Atomic Energy Agency study the angular distribution of gamma-rays emitted from a neutron capture reaction with polarized neutrons. This is the basis of CP-violation research experiments using nuclear reactions. In particle physics CP-violation is one of the origins of the matter universe; however, only tiny violations have thus far been observed. Unknown CP-violating processes are sought through various …
