How many elementary particles have been discovered?
6 Quarks (Up, Down, Charm, Strange, Top, Bottom) 6 Leptons (Electron, Muon, Tau, Electron Neutrino, Muon Neutrino, Tau Neutrino) 5 Bosons (Photon, W+,W- & Z Bosons, Gluon) Overall 17
How many particles have been discovered so far?
6 Quarks (Up, Down, Charm, Strange, Top, Bottom) 6 Leptons (Electron, Muon, Tau, Electron Neutrino, Muon Neutrino, Tau Neutrino) 5 Bosons (Photon, W+,W- & Z Bosons, Gluon) Overall 17
When was Muon neutrino created?
Muon neutrino was created in 1962.
What are the three particles in the lepton family?
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.
How was the Solar neutrino problem solved?
The problem was that the Sun should output a lot more electron neutrinos then were measured. This meant that the model describing the interior of the Sun would be wrong, but it was working very well in predicting other things. It was finally solved when something called neutrino oscillation was discovered. It turned out that (this might be a bit technical) the interaction state of a neutrino was not equal to its mass or propagation state. In short, this meant that electron neutrino's could become muon or tau neutrino's after a while (and change back again after that). After this people began looking for muon and tau neutrinos coming from the Sun and together with the electron neutrino number they added up to the amount the Solar model predicted. The problem was thus solved; the Sun DOES output more electron neutrino's but some of these change into muon or tau neutrinos before they reach the Earth, and since we were initially only looking for electron neutrinos we missed some.

Why is a neutrino released during positron emission?
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!
What is an antielectron neutrino?
An antielectron neutrino is an antileptonic elementary particle - the antiparticle of an electron neutrino.
What is an antimuon neutrino?
An antimuon neutrino is an antileptonic elementary particle which is the antiparticle of a muon neutrino.
Who postulated the existence of the neutrino?
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.
When was Tau neutrino created?
Tau neutrino was created in 2000.
When was Muon neutrino created?
Muon neutrino was created in 1962.
When was Electron neutrino created?
Electron neutrino was created in 1956.

When did Poppa Neutrino die?
Poppa Neutrino died on 2011-01-23.
When was Poppa Neutrino born?
Poppa Neutrino was born on 1933-10-15.
