Abstract
Observations of neutral-current {nu} 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 {sup 8}B shape, the {nu}{sub e} component of the {sup 8}B solar flux is {phi}{sub e}=1.76{sup +0.05}{sub -0.05}( stat){sup +0.09}{sub -0.09}( syst)x10{sup 6} cm{sup -2} s{sup -1} for a kinetic energy threshold of 5 MeV. The non-{nu}{sub e} component is {phi}{sub {mu}}{sub {tau}}=3.41{sup +0.45}{sub -0.45}(stat){sup +0.48}{sub -0.45}(syst)x10{sup 6}= cm{sup -2} s{sup -1} , 5.3{sigma} greater than zero, providing strong evidence for solar {nu}{sub e} flavor transformation. The total flux measured with the NC reaction is {phi}{sub NC}=5.09{sup +0.44}{sub -0.43}(stat){sup +0.46}{sub -0.43}(syst)x10{sup 6} cm{sup -2} s{sup -1} , consistent with solar models.
