Results from the Sudbury Neutrino Observatory Phase III

The third and last phase of the Sudbury Neutrino Observatory (SNO) used a technique independent of previous methods, to measure the rate of neutral-current interactions in heavy water and determine precisely the total active 8B solar neutrino flux. The total flux obtained is , in agreement with previous measurements and standard solar models. Results from a global analysis of solar and reactor neutrino give and degrees with a reduced uncertainty on the mixing angle compared to previous phases.
