anti-neutrino

An anti-neutrino is a tiny, nearly massless particle produced during certain nuclear reactions, such as those in the sun or nuclear reactors. It is the antimatter counterpart of a neutrino, meaning it has similar properties but opposite quantum characteristics, specifically certain quantum numbers related to lepton properties. Anti-neutrinos rarely interact with matter, making them challenging to detect. They play a key role in processes like nuclear decay and particle physics experiments, helping scientists understand fundamental forces and the universe's composition. In essence, anti-neutrinos are elusive, fundamental particles that provide insights into the workings of the universe at the smallest scales.
