neutrino oscillation

[nü¦trē·nō ‚äs·ə′lā·shən]
(particle physics)
A phenomenon in which a neutrino in one of the three known flavor states (electron neutrino, mu neutrino, or tau neutrino) becomes a mixture of flavor states that changes back and forth periodically as the neutrino travels through space; it will occur if neutrinos have mass and if each flavor state is a mixture of different mass states.

where [alpha] can be e, [mu], or [tau] and U is the 3x3 unitary leptonic mixing matrix known as the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix [23, 78].
With the recent determination of [[theta].sub.13], for the first time, a clear and comprehensive picture of the three-flavor leptonic mixing matrix has been established.
