(particle physics)
The antiparticle to the neutrino; it has zero mass, spin ½, and positive helicity; there are two antineutrinos, one associated with electrons and one with muons.

For the measurement of anti-neutrinos it made in 2012, the Daya Bay collaboration has been named runner-up for breakthrough of the year from Science magazine.
Reactors, Heeger said, are a fertile source of anti-neutrinos, and measuring how they change during their short flights from the reactor to the detector, gives a basis for calculating a quantity called the "mixing angle," the probability of transformation from one flavor into another.
The existence of neutrinos and anti-neutrinos - particles that are almost massless and which travel at light speed from one side of the earth to the other - was confirmed more than 50 years ago.
This would result in the continuous creation of lithium-8 isotopes that would rapidly decay, producing huge numbers of anti-neutrinos, which could then be used in practical experiments.
Based on the unprecedently clear geo anti-neutrino data, the answer is no, say the UMass Amherst physicists.
An apparent breakthrough came in May, when scientists at the Los Alamos National Laboratory in New Mexico announced that they had observed muon antineutrinos turning into electron anti-neutrinos in a high-energy particle experiment.
It will be sensitive to both neutrinos and anti-neutrinos, which interact with matter in different ways.
