SNO: Predictions for Ten Measurable Quantities


The survival probabilities as a function of neutrino energy. For each of the six best-fit globally acceptable neutrino oscillation solutions, the viewgraph shows the survival probability for electron type neutrinos as a function of energy. The results are averaged over one year.
Black and White Viewgraph

The relative CC recoil energy spectra for six oscillation solutions. The viewgraph shows the rates, (R(Ee), predicted by different best-fit oscillation solutions as a function of the electron recoil energy, Ee, divided by the rate predicted by the standard solar model and no neutrino oscillations.
Black and White Viewgraph
The fractional shift in the average electron recoil energy. The viewgraph shows T, the fractional change in the average electron recoil energy, , for the six currently allowed neutrino oscillation solutions. The error bars for the neutrino scenarios represent the 99% C.L. allowed regions for the currently favored neutrino oscillation solutions. The estimated experimental error bar is shown on the far right. For an undistorted 8B neutrino energy spectrum, the average recoil energy is denoted by T0. The results are calculated assuming a 5 MeV threshold for the CC reaction.
Color Viewgraph

The neutral current to charged current double ratio. The viewgraph shows, for a 5 MeV threshold for the CC measurement, the predicted double ratio of Neutral Current to Charged Current for different neutrino scenarios. The error bars for the neutrino scenarios represent the 99% C.L. allowed regions for the currently favored neutrino oscillation solutions. The estimated experimental error bar is shown on the far right.
Color Viewgraph
The neutral current to charged current double ratio. The viewgraph shows the same ratio as in the previous viewgraph but for an 8 MeV CC threshold. The error bars represent the 99% C.L. allowed regions for the currently favored neutrino oscillation solutions. The combined 3 calculational and measurement errors are estimated to be smaller than the size of the black dots indicating the best fit values.
Color Viewgraph

The neutrino-electron scattering to charged current double ratio. The viewgraph shows, for a 5 MeV electron recoil energy threshold, the predicted double ratio of Neutrino-Electron Scattering to Charged Current for different neutrino scenarios. The error bars for the neutrino scenarios represent the 99% C.L. allowed regions for the currently favored neutrino oscillation solutions. The estimated experimental error bar is shown at the far right.
Color Viewgraph
The percentage difference between the night and the day CC rates. The viewgraph shows for different neutrino scenarios the percentage difference between the predicted CC rate in SNO at night and the CC rate in the day. The results were calculated with a CC threshold of 5 MeV for the total electron recoil energy. The error bars represent the 99% C.L. allowed regions for the currently favored neutrino oscillation solutions.
Color Viewgraph

The [NC]/[CC] double ratio versus the day-night asymmetry. The viewgraph shows the fractional difference in percent of the neutral current versus charged current double ratio, [NC]/[CC], from the no oscillation value of 1.0, versus the day-night difference, AN-D in percent. The standard model value of AN-D is 0.0. For the six currently preferred oscillation solutions, the error bars represent the 99% C.L. regions for acceptable fits to all the available neutrino data. Estimated error contours for SNO are shown at the 1, 2, 3, and 5 levels relative to the no oscillation solution which lies at (0,0).
