Neutrino physics perspectives with Hyper-Kamiokande

The Hyper-Kamiokande experiment is a proposed next generation underground water Cherenkov detector. It will serve as a far detector of a long baseline neutrino oscillation experiment envisioned for the upgraded J-PARC beam, and is capable of observing – far beyond the sensitivity of the Super-Kamiokande detector – proton decays, atmospheric neutrinos, and neutrinos from astronomical origins. The baseline design of Hyper-Kamiokande is based on the highly successful Super-Kamiokande, but with a 20 times larger detector and higher beam power.
