Antineutrino

An antineutrino is the antimatter equivalent particle of the neutrino. It is produced in nuclear beta decay as a balance to the electron emitted by the nucleus. Neutrinos and antineutrinos only interact with other matter particles via the weak nuclear force, and consequently their properties do not differ greatly.
