Latest solar neutrino analysis results from Super-Kamiokande

Not scheduled


Dr Yuuki Nakano (Kobe University)


Super-Kamiokande (SK), a $50$ kton water Cherenkov detector in Japan, is observing solar studying the effects of both the solar and terrestrial matter density on neutrino oscillations: a distortion of the solar neutrino energy spectrum would be caused by the edge of the Mikheyev-Smirnov-Wolfenstein resonance in the solar core, and terrestrial matter effects would induce a day/night solar neutrino flux asymmetry. On 2018 May, we finished taking data of SK-IV and started the refurbishment work toward SK-Gd. In this poster presentation, we overview the latest solar neutrino results in SK-IV, for example, the precise measurement of 8B solar neutrino flux, its energy spectrum and oscillation parameters. In addition, we discuss the future prospect of the new phase of SK-V (SK-Gd) including the background reduction thanks to the refurbishment work.
