Antineutrino vs. Neutrino

Antineutrinonoun

(particle) The antiparticle of the neutrino.

Antineutrinonoun

The antiparticle of a neutrino. Each type of neutrino has a corresponding antineutrino.

Antineutrinonoun

the antiparticle of a neutrino

Neutrinonoun

An elementary particle that is classified as a lepton, and has an extremely small but nonzero mass and no electric charge. It interacts with the surroundings only via the weak force or gravitation, making it very difficult to detect.

Neutrinonoun

an elementary particle with zero charge and zero mass

Neutrino

A neutrino ( or ) (denoted by the Greek letter ν) is a fermion (an elementary particle with spin of 1/2) that interacts only via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero.
