Pontecorvo's Original Oscillations Revisited

Abstract

We show that a left-handed neutrino ${\nu }_L$ can oscillate into its $CP$- conjugated state ${\bar{\nu }}_R$ with maximal amplitude, in direct analogy with $K^0-{\bar{K}}^0$ oscillations. Peculiarities of such oscillations under different conditions are studied.
