Research Description

Currently, I am involved in the Super-Kamiokande experiment in Kamioka, Gifu Prefecture, the Tokai-Kamioka Long Baseline Neutrino Oscillation Experiment (T2K), which injects accelerator neutrinos from Tokai Village, Ibaraki Prefecture, into the Super-Kamiokande, and the Hyper-Kamiokande experiment, scheduled to begin in 2027.

Neutrinos have been particles which we do not know if they have mass or not since their discovery, but Super-Kamiokande and other experimets have revealed that they have mass. Recent T2K studies have also begun to show signs of CP violation in neutrinos, which could explain why particles and antiparticles, which were equal in number in the early universe, are now overwhelmingly dominated by particles. Some of main purposes of Hyper-Kamiokande are observing this CP violation and searching for proton decays.

Neutrinos are thus a very interesting research subject with major implications for particle physics and astrophysics.
