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 8 B 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 Δm 2 between the two mass eigenstates ranges from about 3 to 19 × 10 -5 eV 2 , while the mixing angle θ is in the range of tan 2 θ ≈ 0.25-0.65. © 2002 Elsevier Science B.V.
