Description
Observations of neutral-current ν 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 8 B shape, the ν e component of the 8 B solar flux is φ e= 1.76− 0.05+ 0.05 (stat)− 0.09+ 0.09 (syst)× 10 6 cm− 2 s− 1 for a kinetic energy threshold of 5 MeV. The non-ν e component is φ μ τ= 3.41− 0.45+ 0.45 (stat)− 0.45+ 0.48 (syst)× 10 6 cm− 2 s− 1, 5.3 σ greater than zero, providing strong evidence for solar ν e flavor transformation. The total flux measured with the NC reaction is φ NC= 5.09− 0.43+ 0.44 (stat)− 0.43+ 0.46 (syst)× 10 6 cm− 2 s− 1, consistent with solar models.
