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 the rate of ve + d → p + p + e- interactions produced by 8B solar neutrinos at the sudbury neutrino observatory

Q. R. Ahmad, +205 more
TL;DR: In this paper, the total flux of 8B neutrinos was determined to be (5.44±0.99)×106 cm−2 s−1, in close agreement with the predictions of solar models.
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

Electron energy spectra, fluxes, and day-night asymmetries of 8B solar neutrinos from measurements with NaCl dissolved in the heavy-water detector at the Sudbury Neutrino Observatory

TL;DR: In this article, a statistical separation of charged-current events from other types based on event-isotropy criteria was made to extract the effective electron recoil energy spectrum, which is consistent with those expected for neutrino oscillations with the so-called large mixing angle parameters.
