Abstract

A model of neutrino oscillation experiments is constructed. The experiments incorporated are: solar neutrinos (Chlorine, Gallium, Super-K, and SNO), reactor neutrinos (Bugey and CHOOZ), beam stop neutrinos (LSND decay at rest and decay in flight), and atmospheric neutrinos. Utilizing this model and the standard three-neutrino mixing extension of the standard model, the data are analyzed. Solutions for the mixing angles and mass-squared differences are found to occur in pairs corresponding to the interchange Δm122Δm232\Delta m^2_{12} \leftrightarrow \Delta m^2_{23}. Two pairs of solutions are found that reasonably reproduce the data, including the LSND data. These solutions are θ120.5\theta_{12}\approx 0.5, θ130.1\theta_{13}\approx 0.1, θ230.7\theta_{23}\approx 0.7, Δm1225×105\Delta m^2_{12} \approx 5\times 10^{-5} eV2^2 and Δm2320.2\Delta m^2_{23} \approx 0.2 eV2^2 or 2.4 eV2^2. Other statistically significant solutions are also found which produce negligible oscillations for the LSND experiments.
