Introduction to the research interests

The search area of the Kuno group is experimental particle physics. To answer fundamental questions such as "What is the origin of the Universe", there are two different experimental approaches in particle physics. One is the high-energy frontier approach and the other is the high-precision frontier approach. The Kuno group adopts the latter, the high-precision approach, and aims to obtain experimental evidence to reveal new physics beyond the current Standard Model of particle physics. In particular, the Kuno group is looking for charged lepton flavor violation that is forbidden in the Standard Model (COMET experiment at J-PARC) or making precise measurements of the lepton universality (PIENU experiment at TRIUMF).
We need to develop novel and unique experimental methods and detection methods. For this purpose, we are developing methods based on advanced technologies: a next-generation muon source with the highest-intensity, the highest-luminosity and the highest-purity in the world, "PRISM"; a future neutrino facility, "neutrino factory"; and a "muon collider" for a new generation of experiments at the energy frontier. We are also aiming to make applications of these technologies to other interdisciplinary fields, and also for technology transfer and spin-off to industry.
