Meaning and Definition
The antiparticle of a neutrino.
A subatomic elementary particle that has the same mass as a neutrino but opposite lepton number and, in some cases, opposite helicity; it is emitted during certain types of radioactive decay, such as beta decay.

Common Mistakes When Using “antineutrino”
- Confusing it with a neutrino. Spelling as two words: 'anti neutrino'. Incorrectly assuming it has opposite charge (both are neutral).
FAQ
Frequently Asked Questions
No. Both neutrinos and antineutrinos are electrically neutral. Their difference lies in their lepton number and other quantum properties.
Not with our eyes. They interact so weakly with matter that enormous, sensitive detectors are required to observe the rare interactions.
They are produced in nuclear reactions, like those in the sun, nuclear reactors, and during radioactive decay processes on Earth and in space.
No. Their extremely weak interaction with matter means they pass through the Earth and our bodies without any harmful effects.
The antiparticle of a neutrino.
Antineutrino is usually technical/scientific in register.
Antineutrino: in British English it is pronounced /ˌænti.njuːˈtriː.nəʊ/, and in American English it is pronounced /ˌæn.t̬i.nuːˈtriː.noʊ/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'Anti-' means opposite, and a 'neutrino' is a tiny neutral particle. So, an antineutrino is the opposite twin of a neutrino.
Conceptual Metaphor
The ANTIPARTICLE IS A MIRROR IMAGE. An antineutrino is often conceptualised as a neutrino moving backwards in time.
