Status of the neutrino decay solution to the solar neutrino problem

Abstract

We re-examine the neutrino decay solution to the solar neutrino problem in the light of the SuperKamiokande (SK) data. For the decay solution the SK spectrum data by its own can provide a fit comparable to the fit obtained from the MSW solution. However when one combines the results from the total rates of the ${}^{37}Cl$ and ${}^{71}Ga$ experiments the fit becomes much poorer.
