Connecting particle physics and astrophysics by using neutrinos,
we study how the universe has been evolved from the "quantum fluctuations" in the early universe.

Purpose and Significance of the Research


 We will attack the outstanding problems in the study of the early universe: inflation, the dark matter, the origin of the asymmetry between matter and antimatter, and the massive black holes. Those problems are addressed by the most-advanced neutrino experiment Hyper-Kamiokande, the CMB telescope Simons Observatory, the dark matter experiment XENON, and the cosmic neutrino telescope IceCube. A major synergistic effect can be achieved by consolidating the development of state-of-the-art technologies (photodetectors, electronic circuits, large-scale data, and AI development and analysis). This proposed system will support young researchers under an independent research environment and to circulate beyond their respective experiments and foster the next generation international researchers.
