On the Oscillation Length Resonance in the Transitions of Solar and Atmospheric Neutrinos Crossing the Earth Core

Assuming two-neutrino mixing takes place in vacuum, we study in detail the conditions under which the ν2 → νe and νμ → νe (νe → νμ(τ)) transitions in the Earth are strongly enhanced by the neutrino oscillation length resonance when the neutrinos cross the Earth core. We show, in particular, that the neutrino oscillation length resonance is operative also in… (More)
