Query: Gravitationally--Induced Three--Flavor Neutrino Oscillations as a
  Possible Solution to the Solar Neutrino Problem   Neutrinos can undergo flavor--oscillations if they possess flavor--dependent
couplings to the surrounding gravitational field (the VEP mechanism). The
neutrino fields can be massless, in accord with the Minimal Standard Model, but
at the expense of the Einstein Equivalence Principle. We show that it is
possible to explain the observed Solar Neutrino data from the various
experiments using the VEP solution in a realistic three--generation framework,
and further note how the three--flavor model can offer larger allowed regions
of parameter space over the two--flavor models.
