Effect of transmission through the Earth on neutrino oscillations

Large transformation and regeneration phenomena are calculated to result from transmission through the Earth of neutrinos whose E(MeV)/Δ$m^2$(${\mathrm{eV}}^2$) lie in the vicinity of ${10}^6$–${10}^7$. As a result large time-of-night and seasonal variations are predicted for solar neutrinos in this parameter range.
