A Galactic supernova (SN) axion signal would be detected in a future neutrino Mton- class water Cherenkov detector, such as the proposed Hyper-Kamiokande in Japan.

Abstract

A Galactic supernova (SN) axion signal would be detected in a future neutrino Mton- class water Cherenkov detector, such as the proposed Hyper-Kamiokande in Japan. The main detection channel for axions is absorption on the oxygen nuclei in the water. The subsequent oxygen de-excitation leads to a potentially detectable gamma signal. In this contribution we present a calculation of the SN axion signal and discuss its detectability in Hyper-Kamiokande.
