Description
The Sudbury Neutrino Observatory (SNO) is a water imaging Cherenkov detector. Its usage of 1000 metric tons of D2O as target allows the SNO detector to make a solar-model independent test of the neutrino oscillation hypothesis by simultaneously measuring the solar νe flux and the total flux of all active neutrino species. Solar neutrinos from the decay of 8B have been detected at SNO by the charged-current (CC) interaction on the deuteron and by the elastic scattering (ES) of electrons. While the CC reaction is sensitive exclusively to νe, the ES reaction also has a small sensitivity to νμ and ντ. In this paper, recent solar neutrino results from the SNO experiment are presented. It is demonstrated that the solar flux from 8B decay as measured from the ES reaction rate under the no-oscillation assumption is consistent with the high precision ES measurement by the Super-Kamiokande experiment. The νe flux deduced from the CC reaction rate in SNO differs from the Super-Kamiokande ES results by 3.3σ. This is evidence for an active neutrino component, in additional to νe, in the solar neutrino flux. These results also allow the first experimental determination of the total active 8B neutrino flux from the Sun, and is found to be in good agreement with solar model predictions
