Sterile neutrino is ruled out.

"A high-precision neutrino experiment has delivered a decisive result that challenges a long-standing explanation for mysterious signals seen in earlier studies. By carefully dissecting how neutrinos transform as they travel, researchers have narrowed the range of viable theories and set the stage for a new phase of investigation.

A sterile neutrino means a neutrino that formed straight from electromagnetic fields. If that particle exists, that means it formed in the sensor itself. The thing. That can form. The neutrino. Directly from wave movement. Are the Schwinger effect and the wave-particle duality. Even if a sterile neutrino exists, it will not remain sterile. For. A long time. And that means it's almost impossible to confirm those sterile neutrinos. 

Neutrino is the second generation of fermions. Or, sharper saying, neutrinos are members of the lepton family. Leptons are electrons, muons, and tauons. Those particles form in a weak interaction with leptons. We know three types of neutrons. Tau neutrino, electron neutrino and muon neutrino. Those particles are transformations to electrons, tau particles, and muons. 

Or, they form in reactions from muons, taus, and electrons. This means that we don’t actually know neutrinos. This means that. We don’t know. The neutrino that formed in the Schwinger effect. We don’t know. The neutrino, that form. It is direct. In. The wave-particle duality. Neutrinos are formed in the interaction when the weak nuclear force interacts with leptons. 

Sterile neutrino is ruled out, at least for a while. For being sterile, the neutrino must form in a sensor. Otherwise, if a neutrino travels only a short distance, it turns dirty. Neutrino takes quantum fields with it. This means that the neutrino turns dirty. We can call those quantum fields. As “quantum plague”. 

And. Even if a neutrino stays in a static position, it will turn dirty because the “quantum wind” makes it messy. A sterile neutrino cannot exist in our universe, or its existence remains for such a short time. That means we cannot see it. So even if a neutrino forms in the fusion reactor. It turns dirty before it reaches the sensor. The problem with sterile neutrino hunting is that nobody has seen a sterile neutrino. Reseachers see those dirty neutrinos quite often. 

Quantum fields touch those neutrinos. And those fields are left as a plague on those neutrinos that neutrino sensors detect. But the thing that makes it almost impossible to detect and confirm the sterile neutrino is that. The system must know what kind of fields are touched on those neutrinos. So, the system calculates the thickness of that quantum plague. 

If reseachers want to find sterile neutrinos, they must know how much energy, or how thick the quantum layer is through which neutrinos are collected. While their journey to Earth. But. For making those calculations, the system must know the precise point of the Big Bang, or where the neutrinos formed. Then the system must know all quantum fields between the point where the neutrino formed. And then it can calculate the quantum field that is on the neutrino. But as we know, this kind of mission is impossible. Another thing that rules out the existence of the sterile neutrino is the Pauli exclusion principle. 

“In quantum mechanics, the Pauli exclusion principle (German: Pauli-Ausschlussprinzip) states that two or more identical particles with half-integer spins (i.e. fermions) cannot simultaneously occupy the same quantum state within a system that obeys the laws of quantum mechanics. This principle was formulated by Austrian physicist Wolfgang Pauli in 1925 for electrons, and later extended to all fermions with his spin–statistics theorem of 1940.” (Wikipedia, Pauli exclusion principle). 

If. We expand this model to the universe’s scale. That means that because a neutrino is a fermion, there can be only one sterile neutrino in the entire universe. The Pauli exclusion principle means that there are no two fully identical neutrinos in the universe. So, if the sterile neutrino exists, that means there cannot be two of them. All sterile neutrinos. Are identical. That situation is impossible. If. We want to follow the Pauli exclusion principle.
