In the global search for dark matter, the XENONnT experiment at the INFN Laboratori Nazionali del Gran Sasso (LNGS) stands out as one of the world’s most sensitive detectors in the field. This international collaboration, comprising over 190 scientists from 30 institutions worldwide, has achieved a major technological breakthrough: a significant reduction in radioactive background noise, a feat never previously achieved in rare-event physics experiments. The core of this innovation is a cryogenic distillation system that purifies the liquid xenon …

The Vera C. Rubin Observatory released its first images taken with the world’s largest digital camera on June 23, 2025 (local time). This marks the beginning of the Legacy Survey of Space and Time (LSST), a large-scale imaging project. Many Japanese researchers, including ones from the Kobayashi-Maskawa Institute for the Origin of Particles and the Universe (KMI) at Nagoya University and the National Astronomical Observatory of Japan (NAOJ), are involved in LSST, and new scientific discoveries are expected through collaboration …

The XENON collaboration is an international collaboration between the United States, Europe and Japan, involving the KMI and ISEE at the Nagoya University, the Kavli IPMU, WPI at the University of Tokyo, the Institute for Cosmic Ray Research at the University of Tokyo and Kobe University. The collaboration has observed for the first time the scattering of neutrinos and xenon nuclei produced by the Sun in the XENONnT experiment, a dark matter search experiment currently in operation. The results were …

A joint research group led by Professor Takahiro Tanaka (Kyoto University) and Associate Professor Yuko Urakawa (KEK, and Designated Associate Professor at KMI) has applied the “split universe approach,” in which the universe is recomposed into a coarse-grained mosaic art, to greatly simplify numerical calculations of primordial gravitational waves. This approach enables the numerical calculation of various models of the universe, including those that have been difficult to analyze due to the complex numerical calculations required. It is expected to …

The J-PARC muon g-2/EDM experimental group, which includes Professor Toru Iijima, Designated Lecturer Kazuhito Suzuki, Associate Professor Kenji Inami, and graduate students Kazuji Sumi, Koichi Ueda, and Ayaka Kondo, has successfully cooled and accelerated positively charged muons for the first time in the world. This achievement marks a major step toward launching an ultra-precise verification of the Standard Model. Additionally, a completely new imaging technique using accelerated muons is being considered for various applications, including muon microscopy and interdisciplinary research …
