Nutrinos never been detected?How come they are shown in reaction equationS?

Question

Residue in reaction equations are really energy dissipation rather than Neutrinos which was postulated to explain mass loss?

Answer 1

Neutrinos were first theorized in the late 1920's as scientists observed a radioactive processknown as beta decay. Beta decay occurs when a neutron in the nucleus ofan atom breaks down or "decays" into a proton and a high-speed electron. As scientists were observing this phenomenon, they noticed that some of the energy had completely vanished. This was a direct violation of the Law of Conservation of Matter and Energy but thankfully after the years The Universal model did not change to account for the loss

Wolfgang Pauli theorized a solution.He proposed that the energy was not lost but merely undetected. This energy,he said, was changed into a strange, minute, subatomic particle with nocharge and likely no mass. This particle can only bedetected when it interacts with ordinary matter. But because it is so small the particles interaction with matter cannot be detected

The neutrino was eventually detected in the bottom of a nuclear reactor shaft in 1956 proving Pauli's theory correct. Three different kinds, or "flavors", of neutrinos have been detected: the electron, muon and tau. Also astonishing was the discovery of the pion particle which accounts for the strong nuclear force between neutrons and protons (they exchange a pion ).When a particle meets an antiparticle, they annihilateeach other and evaporate into a tremendous amount of energy. Therefore a pion has an incredibly short lifetime of one hundred millionth of a second (10-8 second).

Now about Missing mass and do neutrinos have mass

Many scientists believe this missing mass takes the form of neutrinos and that neutrinos are not massless. If the neutrino does have mass, it is extremely small. The combined mass of zillions of millions of them could account for this missing mass. If even one of the three forms has a mass of only ten eV - roughly one ten billionth of one percent the mass of the hydrogenatom - they would have enough mass to account for the missing matter.

The only proof that Neutrinos have mass can be found in MINOS fermilab experiment here:

Answer 2

In the first place neutrinos have been 'invented' because of the need of conservation of energy, magnetic moment (spin), momentum and number of leptons.
Six kinds of neutrinos are detected now.
