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.

Out of these we have discussed in Section 2 how the mediation of [mathematical expression not reproducible] gives type-II seesaw contribution to neutrino masses matching with available neutrino oscillation data at 1[sigma]-3[sigma] levels for all types of hierarchies: NH, IH, and QD.
She is known for her pioneering work in high-energy particle physics and especially for major contributions to the study of neutrinos, being a leader in the development and analysis of neutrino oscillation measurements.
Is it possible to describe neutrino oscillation dynamics with Bogoliubov-deGennes theory, in lieu of using standard Schrodinger-type wave equation [6]?
Researchers plan additional experiments to seek further evidence of neutrino oscillation. In Japan and the United States, they propose to use accelerators to fling neutrinos at targets several hundred kilometers away.
In neutrino oscillation experiments a value of [C.sup.2.sub.[nu]] [approximately equal to] [10.sup.-2] has been employed.
Their presence is "very strong evidence" that a muon antineutrino can transform itself into an electron antineutrino through a hypothetical process that theorists call neutrino oscillation, says Fred J.
However, from the neutrino oscillation experiments, we got convinced that at least two neutrinos have nonzero mass.
This theory proposes a resonance between neutrino oscillation and the structure of the center of the sun.
After the precise measurement of reactor mixing angle [[theta].sub.13] in T2K, MINOS, Double Chooz, Daya Bay, and RENO experiments [1-5], five parameters in the neutrino sector have been well measured by neutrino oscillation experiments.
Out of sixty possibilities, only fifty-four are found to be compatible with the neutrino oscillation data [21] for texture structures having one zero element and equal matrix elements in the vanishing minor and equal cofactors in the neutrino mass matrix (1TEC) only fifty-two cases are able to survive the data [26, 27].
Their unprecedented lightness and the peculiar shape of the leptonic mixing pattern reflected by the neutrino oscillation phenomena make the origin of neutrino mass a central question of the present-day high-energy physics.
