Adiabatic Analysis of Gravitationally-Induced Three-Flavor Neutrino Oscillations

Some implications of the proposal that flavor nondiagonal couplings of neutrinos to gravity might resolve the solar neutrino problem are considered in the context of three neutrino flavours. Using an adiabatic approximation iso-SNU curves are calculated for the neutrinos which most likely contribute to the observed solar neutrino deficiency. We show that results obtained with two-flavor models can be recovered, and discuss the effects of the addition of a third flavor. Some results are obtained for this case, and these values are compared with recent experimental data.
