Abstract

We re-examine MSW solutions of the solar neutrino problem taking (a) the results on total rates and the electron energy spectrum from the 825 day SuperKamiokande (SK) data, (b) those on total rates from the Chlorine and Gallium experiments, and (c) moments of the SK electron spectrum. A salient feature of our analysis is the inclusion of the correlations between the theory errors in the global-fit using the data on the total rates and SK electron energy spectrum. Best fit values for the mixing angle and mass splitting are found for oscillations to sequential and sterile neutrinos and the 90% C.L. allowed regions are determined.
