“…The goal of this paper is to assess the impact of recent SNO measurements [1,2,3] on the allowed regions of neutrino oscillation parameters and on the predicted values of the most important future solar neutrino observables. The SNO collaboration has reported a neutral current (NC) measurement of the active 8 B solar neutrino flux and related measurements of the day-night asymmetry, as well as improved determinations of the charged current (CC) and neutrino-electron scattering rate.…”

We present "Before and After" global oscillation solutions, as well as predicted "Before and After" values and ranges for ten future solar neutrino observables (for BOREXINO, KamLAND, SNO, and a generic p − p neutrino detector). The "Before" case includes all solar neutrino data (and some theoretical improvements) available prior to April 20, 2002 and the "After" case includes, in addition, the new SNO data on the CC, NC, and day-night asymmetry. We have performed global analyses using the full SNO day-night energy spectrum and, alternatively, using just the SNO NC and CC rates and the day-night asymmetry. The LMA solution is the only currently allowed MSW oscillation solution at ∼ 99% CL. The LOW solution is allowed only at more than 2.5σ, SMA is now excluded at 3.7σ or 4.7σ depending upon analysis strategy, and pure sterile oscillations are excluded at more than 4.7σ. Small mixing angles are "out" (pure sterile is "way out"); MSW with large mixing angles is definitely "in." Vacuum oscillations are allowed at 3σ, but not at 2σ. Precise maximal mixing is excluded at 3.2σ for MSW solutions and at more than 2.8σ for vacuum solutions. Most of the predicted values for future observables for the BOREXINO, KamLAND, and future SNO measurements are changed only by minor amounts by the inclusion of the recent SNO data. In order to test the robustness of the allowed neutrino oscillation regions that are inferred from the measurements and the predicted values for future solar neutrino observables, we have carried out calculations using a variety of strategies for analyzing the SNO and other experimental data.

“…The experimental confirmation that atmospheric and solar neutrinos do oscillate [1,2], and therefore have mass, represents the first solid clue for the existence of new physics beyond the Standard Model [3]. Results from experiments carried out with neutrinos produced in artificial sources, like reactors and accelerators, strongly support the fact that neutrinos are massive [4,5].…”
