Determination of solar neutrino oscillation parameters using 1496 days of Super-Kamiokande-I data
A number of different fits to solar neutrino mixing and mass square difference were performed using 1496 days of Super-Kamiokande-I's solar neutrino data. These data select two allowed areas at large neutrino mixing when combined with either the solar 8B flux prediction of the standard solar model or the SNO interaction rate measurements. A global fit combining SK data with the solar neutrino interaction rates measured by Homestake, SNO, Gallex/GNO and SAGE prefers a single allowed area, the Large Mixing Angle solution, at the 98.9% confidence level. The mass square difference Δm2 between the two mass eigenstates ranges from about 3 to 19 × 10-5 eV2, while the mixing angle θ is in the range of tan2θ ≈ 0.25-0.65. © 2002 Elsevier Science B.V.
