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.

I provide the only first principles derivation of the Weinberg angle as a further application of the discrete symmetry subgroups of SU(2) that I used for the first principles derivation of the mixing angles for the neutrino mixing matrix PMNS [1] in 2013 and of the CKM quark mixing matrix [2] in 2014.
