(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.
