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 …

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 …

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 …

Assistant Professor Takeshi Kobayashi of the Kobayashi-Maskawa Institute for the Origin of Particles and the Universe (KMI), Nagoya University, proposes that an elementary particle called the axion could have been the origin of the cosmic structure of our universe. Astrophysical studies in the past decades have established that the cosmic structure, including galaxies and galaxy clusters, arises from tiny fluctuations in the energy density when the universe was young; however the origin of this primordial density fluctuation still remains one …

Japan’s High Energy Accelerator Research Organization (KEK) has been steadily improving the performance of its flagship electron-positron collider, SuperKEKB, since it produced its first electron-positron collisions in April 2018.  At 20:34 on 15th June 2020, SuperKEKB achieved the world’s highest instantaneous luminosity for a colliding-beam accelerator, setting a record of 2.22×1034 cm-2 s-1. Previously, the KEKB collider, which was SuperKEKB’s predecessor and was operated by KEK from 1999 to 2010, had achieved the world’s highest luminosity, reaching 2.11×1034 cm-2 s-1. KEKB’s record …
