Abstract
Observations of neutral-current interactions on deuterium in the Sudbury Neutrino Observatory are reported. Using the neutral current (NC), elastic scattering, and charged current reactions and assuming the standard shape, the component of the solar flux is for a kinetic energy threshold of 5 MeV. The non- component is , greater than zero, providing strong evidence for solar flavor transformation. The total flux measured with the NC reaction is , consistent with solar models.

Nobel Prize—Neutrinos Oscillate
Published 7 October 2015
The 2015 physics Nobel Prize goes to the discoverers of the strange ability of neutrinos to transform among three “flavors.”
