Title: "Super-Kamiokande and Solar Neutrinos"


Neutrino oscillation is widely believed to bring about what is known as the solar neutrino problem: Relative rates of solar neutrinos observed in different experiments seem inconsistent with the fuel cycle in the sun. Manipulation of parameters in solar models do alter rate expectations but do not allow to reproduce the observed pattern. If on the other hand the electron type neutrinos originating in the sun oscillate into other flavors, the measured rates can be interpreted with standard solar models. Super-Kamiokande is the first in a series of experiments looking for decisive signatures of neutrino oscillation in the solar neutrino sector. Data from 825 live days of solar neutrino observation will be discussed in this context.
