Description
The project and building of a twin Megaton neutrino detector as HyperKamiokande both
in Japan and possibly, in South Corea will provide in near future the most advanced (in few MeV up to several GeVs energy windows) telescope of galactic and nearby (Andromeda, LMC..) Supernova (SN) thermal neutrino events by their SN neutrino burst. These rare SN must be located within one or a few Mpc. The underground HK may also better trace the atmospheric neutrinos signals testing their precise flavor mixing and their matter-anti matter component (or eventual asymmetry). In this flavor test the same elusive tau neutrino appearence (by atmospheric muon neutrino oscillation at several GeV) may be also be finally
well probed. In addition to astrophysical and (atmospheric and fundamental) physics, the HK may also discover the first multiwave detection of X-gamma photons and their correlated tens MeV (up to GeV) neutrino signals during largest solar flare. Such a physics may combine the solar flare plasma physics with its inner proton proton scattering and with consequent pion and Kaon production . This expected discover,
after SN1987A and Solar neutrino astronomy, will open a third independent solar Neutrino
windows. Foreseen solar neutrino spectra, signature and rate in HK for each flavor will be shown in details. References:
