Abstract

The long baseline between Earth and the Sun makes solar neutrinos an excellent test beam for exploring possible neutrino decay. The signature of such decaywould be an energy-dependent distortion of the traditional survival probability which can be fit for using well-developed and high-precision analysis methods. Here a model including neutrino decay is fit to all three phases of B-8 solar neutrino data taken by the SudburyNeutrino Observatory (SNO). This fit constrains the lifetime of neutrino mass state nu(2) to be > 8.08 x 10(-5) s/eV at 90% confidence. An analysis combining this SNO result with those from other solar neutrino experiments results in a combined limit for the lifetime of mass state nu(2) of > 1.92 x 10(-3) s/eV at 90% confidence.
