Description

The Hyper-Kamiokande experiment is a proposed next-generation water Cherenkov detector. It will consist of two cylindrical tanks, with a fiducial volume of 400 ktonnes, observed by 20 inch high quantum efficiency PMTs with 40% photocathode coverage. Hyper-K will be able to perform indirect WIMP searches, looking for signals from the Sun, the Earth, and the galactic centre. In such areas, WIMPs can be trapped by gravitational potentials and annihilate on other WIMPs. Such annihilations produce neutrinos that can be observed by Hyper-K as an excess above that which is expected from atmospheric neutrinos. Hyper-K will improve the sensitivity of such indirect WIMP searches above the limits that have already been obtained by Super-Kamiokande. Additionally, the high photocoverage gives Hyper-K excellent sensitivity to the low momentum region and low mass WIMPs.
