Solar neutrino oscillation diagnostics at SuperKamiokande and Sudbury Neutrino Observatory

Results for solar neutrino detection from the SuperKamiokande collaboration have been presented recently while those from the Sudbury Neutrino Observa tory are expected in the near future. These experiments are sensitive to th e B-8 neutrinos from the sun, the shape of whose spectrum is well-known but the normalization is less certain. We propose several variables, insensiti ve to the absolute flux of the incident beam, which probe the shape of the observed spectrum and can sensitively signal neutrino oscillations. They pr ovide methods to extract the neutrino mixing angle and mass splitting from the data and also to distinguish oscillation to sequential neutrinos from t hose to a sterile neutrino.
