Résumé

The measurements performed for determining the total active 8B solar neutrino flux at the Sudbury Neutrino Observatory (SNO) were investigated. The measurements were performed without assumptions about the energy dependence of the survival probability. NaCl dissolved in heavy water was used for making the measurements in order to enhance the sensitivity and signature for neutral-current interactions. The hypothesis of maximal mixing at a confidence level equivalent to 5.4σ was found to be inappropriate by the combined results of global solar and neutrino.
