Journal ArticleDOI

Direct evidence for neutrino flavor transformation from neutral current interactions in the Sudbury Neutrino Observatory

Q. R. Ahmad, +205 more
TL;DR: Observations of neutral-current nu interactions on deuterium in the Sudbury Neutrino Observatory are reported, providing strong evidence for solar nu(e) flavor transformation.
Journal ArticleDOI

Measurement of Day and Night Neutrino Energy Spectra at SNO and Constraints on Neutrino Mixing Parameters

Q. R. Ahmad, +205 more
TL;DR: The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates, and a global solar neutRino analysis in terms of matter-enhanced oscillations of two active flavors strongly favors the large mixing angle solution.
Journal ArticleDOI

Measurement of the total active B-8 solar neutrino flux at the Sudbury Neutrino Observatory with enhanced neutral current sensitivity

S. N. Ahmed, +141 more
TL;DR: The Sudbury Neutrino Observatory has precisely determined the total active (nu(x) 8B solar neutrino flux without assumptions about the energy dependence of the nu(e) survival probability.
Journal ArticleDOI

Independent Measurement of the Total Active 8B Solar Neutrino Flux Using an Array of 3He Proportional Counters at the Sudbury Neutrino Observatory

B. Aharmim, +174 more
TL;DR: The Sudbury Neutrino Observatory (SNO) used an array of He3 proportional counters to measure the rate of neutral-current interactions in heavy water and precisely determined the total active (x) B8 solar neutrino flux as discussed by the authors.
Journal ArticleDOI

Determination of the νe and total B8 solar neutrino fluxes using the Sudbury Neutrino Observatory Phase I data set

B. Aharmim, +245 more
- 27 Apr 2007 - 
TL;DR: The phase I data set of the Sudbury Neutrino Observatory (SNO) as discussed by the authors is based on a 0.65 kt-year exposure of heavy water to the solar 8B neutrino flux.
