Wolfgang Pauli
Walter Baade and Fritz Zwicky proposed the existence of the neutron star in 1934. Antony Hewish and Samuel Okoye discovered "an unusual source of high radio brightness temperature in the Crab Nebula" in 1965, which turned out to be the Crab Nebula neutron star.
To preserve the conservation of; energy, momentum, and angular momentum in beta plus decay. Without the neutrino there is a measurable difference between the energy, momentum, and angular momentum of the initial and final particle. The neutrino rectifies this difference and it's existence was actually postulated before it was ever discovered!
Lack of lab equipment, Cowan Reines proved the existence of the neutrino in 1956 but to do that they needed a nuclear reactor as a source of a neutrino flux
An antielectron neutrino is an antileptonic elementary particle - the antiparticle of an electron neutrino.
An antimuon neutrino is an antileptonic elementary particle which is the antiparticle of a muon neutrino.
Neutrinos were first postulated by Wolfgang Pauli in 1930 to explain the missing energy and momentum in beta decay. They were experimentally confirmed by Clyde Cowan and Frederick Reines in 1956 through the detection of electron antineutrinos produced in a nuclear reactor.
They aren't 3 they are in fact 12 if you count anti matter as a separate particle from matter. Electron, muon, tau, electron neutrino, muon neutrino and tau neutrino. The same apply to anti matter positron, anti muon, anti tau, postrin neutrino, anti muon neutrino, and anti tau neutrino.
Actually, we can't even confirm the existence of atoms, let alone subatomic particles. But when scientists conduct experiments, they come to the conclusion that the particles are indeed valid. The more discrete physics becomes, the more theoretical it is.
Tau neutrino was created in 2000.
Electron neutrino was created in 1956.
The charge of a neutrino is neutral, meaning it has no electric charge.
