MSW mediated neutrino decay and the solar neutrino problem
Abstract
We investigate the solar neutrino problem assuming simultaneous presence of MSW transitions in the sun and neutrino decay on the way from sun to earth. We do a global 2-analysis of the data on total rates in Cl, Ga and Superkamiokande (SK) experiments and the SK day-night spectrum data and determine the changes in the allowed region in the - 2θ plane in presence of decay. We also discuss the implications for unstable neutrinos in the SNO experiment.
