Neutrinos are created as a result of certain types of radioactive decay, or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms. These particles are known to exist in three states: as electron neutrinos, muon neutrinos, and tau neutrinos. The neutrino is associated with an antiparticle, called an "antineutrino", which has the same neutral electric charge and half-integer spin as the neutrino, but the spins of neutrinos and antineutrinos, at least ordinarily, have opposite orientations with respect to their directions of motion. Whether or not the neutrino and antineutrino are actually identical particles has not yet been resolved. Recent efforts have settled on searches for a particular form of radioactivity called neutrinoless double-beta decay. Confirmation of the neutrinoless double-beta decay could help identify the neutrino mass hierarchy and scale and provide details to explain why matter dominates over antimatter in the universe.
