Inside the Sudbury Neutrino Observatory: how 1,000 tons of heavy water solved the solar neutrino problem, and how its successor SNO+ is now hunting for neutrinoless double beta decay.
For thirty years, only one-third of the predicted solar neutrinos were arriving at Earth. In 2001, an experiment two kilometers underground in Canada proved that the missing two-thirds had simply changed flavor along the way.
A guided walk through the 2001 PRL by the Sudbury Neutrino Observatory that solved the 30-year solar neutrino problem. SNO measured the total flux of all neutrino flavors from the Sun and compared it to the electron-flavor flux — directly showing solar electron neutrinos converting to other flavors.
