Time Variations of Solar Neutrino Signals and the RSFCN Hypothesis

Abstract

Resonant spin--flavour conversion of neutrinos (RSFCN) in twisting magnetic fields might be at the origin of the apparent anticorrelation between the ${}^{37}$Ar production--rate in the Homestake solar neutrino detector and the solar activity. Moreover, it can account for the results of all solar neutrino experiments reported so far including the recent results of GALLEX and SAGE.
