In some sense they describe the “square root” of geometry and, just as understanding the square root of −1 took centuries, the same might be true of spinors.“ (Wikipedia/Spinor) Unquote

The
neutrino cannot be „sterile“ in the Higgs-Field. A neutrino is a
spinor, if not quaternions. The majorana identity of neutrinos (majorana
particle) indicates a p-violation of neutrinos, also when transiting
from matter into the quantum vacuum by a non-linear coupling factor to
the electroweak force in dimensional transmutations.

(The appearance of both ψ and ψc in the Majorana equation means that the field ψ cannot be coupled to an electromagnetic field without violating charge conservation, so ψ is taken to be neutrally charged. Nonetheless, the quanta of the Majorana equation given here are two particle species, a neutral particle and its neutral antiparticle. The Majorana equation is frequently supplemented by the condition that ψ = ψc (in which case one says that ψ is a Majorana spinor); this results in a single neutral particle. For a Majorana spinor, the Majorana equation is equivalent to the Dirac equation.

Particles
corresponding to Majorana spinors are aptly called Majorana particles.
Such a particle is its own antiparticle. Thus far, of all the fermions
included in the Standard Model, none is described as a Majorana fermion.
However, there is the possibility that the neutrino is of a Majorana
nature. If so, neutrinoless double-beta decay, as well as a range of
lepton-number violating meson and charged lepton decays, are possible. A
number of experiments probing if the neutrino is a Majorana particle
are currently underway.)

The nature of the interaction

The
interaction could also explain muon decay via a coupling of a muon,
electron-antineutrino, muon-neutrino and electron, with the same
fundamental strength of the interaction. This hypothesis was put forward
by Gershtein and Zeldovich and is known as the Conserved Vector Current
hypothesis

Fermi’s four-fermion theory describes the weak
interaction remarkably well. Unfortunately, the calculated cross-section
grows as the square of the energy \sigma \approx G_{\rm F}^2 E^2 ,
making it unlikely that the theory is valid at energies much higher than
about 100 GeV. The solution is to replace the four-fermion contact
interaction by a more complete theory (UV completion)—an exchange of a W
or Z boson as explained in the electroweak theory.

In the original
theory, Fermi assumed that the form of interaction is a contact coupling
of two vector currents. Subsequently, it was pointed out by Lee and
Yang that nothing prevented the appearance of an axial, parity violating
current, and this was confirmed by experiments carried out by
Chien-Shiung Wu.[6][7]

Coupling Constant GF. Fermi’s Theory was the first theoretical effort in
describing nuclear decay rates for Beta-Decay.

The inclusion of
Parity violation in Fermi’s interaction was done by George Gamow and
Edward Teller in the so-called Gamow-Teller Transitions which described
Fermi’s interaction in terms of Parity violating „allowed“ decays and
Parity conserving „superallowed“ decays in terms of anti-parallel and
parallel electron and neutrino spin states respectively. Before the
advent of the electroweak theory and the Standard Model, George
Sudarshan and Robert Marshak, and also independently Richard Feynman and
Murray Gell-Mann, were able to determine the correct tensor structure
(vector minus axial vector, V − A) of the four-fermion interaction

„When neutrinos travel through a dense medium (e.g., in the Sun or in

the Earth), their propagation can be significantly modified by the coherent

forward scattering from particles they encounter along the way. As a

result, the oscillation probability can be rather different than it is in vacuum.

The flavour-changing mechanism in matter was named after Mikhaev,

Smirnov and Wolfenstein (MSW), who first pointed out [1] that there is

an interplay between flavour-non-changing neutrino-matter interactions and

neutrino
mass and mixing. The MSW effect stems from the fact that electron
neutrinos (and antineutrinos) have different interactions with matter
compared

to other neutrinos flavours. In particular, e can have both charged

current and neutral current elastic scattering with electrons, while μ or

have only neutral current interactions with electrons. This fact gives rise to

an extra-potential Ve = ±

p

2GFNe [2], where Ne is the electron density in

matter, GF is the Fermi constant, and the positive(negative) sign applies to

electron-neutrino(antineutrinos).

Therefore, the effective Hamiltonian which governs the propagation of

neutrinos in matter, HM, contains an extra e-e element.“ Unquote
