The latest solar neutrino results in Super-Kamiokande

The results of 1500 days of solar neutrino measurement in Super-Kamiokande are presented, those are absolute solar neutrino flux, flux time variation, energy spectrum, hep flux limit. The precise measurement of the solar neutrino energy spectrum and day-night flux differences are the most important issue to understand neutrino oscillations. So it is very important to precisely determine the energy scale of the detector. In Super-Kamiokande, we have used an electron LINAC and ¹⁶N calibration, and it can reduce the energy scale uncertainty 0.64%.
