An antielectron neutrino is an antileptonic elementary particle - the antiparticle of an electron neutrino.
An antielectron, also known as a positron, is the antimatter counterpart of an electron. It has the same mass as an electron but carries a positive charge instead of a negative charge. When an antielectron and an electron meet, they annihilate each other, releasing energy in the form of photons.
A neutron in the nucleus of the tritium atom decays into a proton and an electron and an antielectron neutrino. The proton remains in the nucleus causing the atomic number to increase by 1 as the atom becomes that of a different element while mass number remains the same, He3. The electron and antielectron neutrino are emitted from the nucleus.

An antimuon neutrino is an antileptonic elementary particle which is the antiparticle of a muon neutrino.
Muon neutrinos were created during the Big Bang, which started approximately 13.8 billion years ago. They are a fundamental particle that is believed to have been produced in the early universe along with other elementary particles.
Tau neutrino was created in 2000.
Electron neutrino was created in 1956.
The three particles in the lepton family are the electron, the muon, and the tau. Each lepton has an associated neutrino (electron neutrino, muon neutrino, and tau neutrino) with which they interact via the weak force.
