Abstract
In the presence of flavor oscillations, muon and tau neutrinos can contribute to the Super-Kamiokande (SK) solar neutrino signal through the neutral current process ; e \Gamma ! ; e \Gamma . We show how to separate the e and ; event rates in SK in a model independent way, by using the rate of the charged current process e d ! p p e \Gamma from the Sudbury Neutrino Observatory (SNO) experiment, with an appropriate choice of the SK and SNO energy thresholds. Under the additional hypothesis of no oscillations into sterile states, we also show how to determine the absolute 8 B neutrino flux from the same data set, independently of the e survival probability.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
