Status and Perspectives of Solar Neutrino Research at Super-Kamiokande

Michael Smy (University of California, Usa)

8B solar neutrino measurements from SNO and Super-Kamiokande have clearly demonstrated solar neutrino flavor conversion and determined neutrino oscillation parameters driving this conversion. 

Current studies at Super-Kamiokande test crucial predictions of the solar neutrino oscillation paradigm such as the transition from conversion driven by the solar electron density to vacuum oscillations in the energy region near three MeV of neutrino energy, the change in survival probability due to the impact of the terrestrial electron density, as well as consistency of solar neutrino oscillation parameters with those determined from anti-neutrinos. 

In the future these analyses will benefit from a reduced energy threshold and new techniques such as improved tagging of cosmogenic radioactive decays.
