Abstract
The SNO Collaboration has completed a combined analysis of 8B solar neutrino data from all three phases of the project. The combined analysis resulted in a total flux of active neutrino flavors from 8B decays in the sun of 5.25±0.16(stat.)−0.13+0.11(syst.)×106cm2s−1. A three-flavor neutrino oscillation analysis combining the SNO results with results of all other solar neutrino experiments and the KamLAND experiment yielded Δm212=(7.41−0.19+0.21)×10−5eV2, tan2θ12=0.446−0.029+0.030, and sin2θ13=(2.5−1.5+1.8)×10−2. The results of the SNO analysis will be presented, along with a discussion of future projects that will seek to study lower energy neutrinos to improve on our knowledge of the properties of neutrinos and the sun.
