A quantum neutrino is an electrically neutral lepton with very small mass and weak interaction strength. Neutrinos are produced in nuclear reactions, particle decays, astrophysical sources, and high-energy collisions. Their flavor oscillations show that flavor states are quantum superpositions of mass states.[1][2][3]

Complex yellow illustration of neutrino flavor oscillation, weak interaction, and propagating quantum phase.

Flavor and mass

Neutrinos are observed in electron, muon, and tau flavors. Oscillation experiments show that these flavor states are not identical to mass states. As a neutrino propagates, relative quantum phases between mass components change, producing a probability for one flavor to be detected as another.

Interactions

Neutrinos do not carry electric or color charge. They interact through the weak force and gravity, which makes them difficult to detect but also valuable messengers from dense or distant environments. Detection typically relies on charged-current or neutral-current weak reactions.

Scientific role

Neutrinos probe solar fusion, supernovae, atmospheric showers, reactors, accelerators, and cosmology. Open questions include the absolute neutrino mass scale, mass ordering, CP violation in the lepton sector, and whether neutrinos are Dirac or Majorana particles.[4]
