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.

At locations both in and outside of Japan, ICRR has conducted research on high-energy cosmic rays, high-energy gamma rays, and neutrinos; for example, the Super-Kamiokande(5) Project has discovered neutrino oscillations and the Tibet AS-gamma Experiment used cosmic rays to observe the sun's cosmic-ray shadow(6).

One of the major developments of the past decade has been the establishing of the existence of neutrino oscillations.
We don't know what it is, but neutrino oscillations are someplace where it might show up," he said.
The theoretical analysis [6], which was based on the interpretations from super K data that the neutrino oscillations between flavors could only occur if the neutrino had a rest mass, was cast in terms of a net transfer of linear momentum, but since it is now known that the neutrino always possesses left-handed helicity, and since it is reported that upon inelastic collision between a neutrino at v ~ c, and a proton or a neutron, the flavor of the neutrino has a very high probability to change--thus the spin magnetic moment property of the particle changes--the analysis is broadened herein to include total angular momentum.
