A neutral subatomic particle with a mass close to zero and half-integral spin, which rarely reacts with normal matter. Three kinds of neutrinos are known, associated with the electron, muon, and tau particle
= muon neutrino. Frequently written μ-neutrino.
A type of neutrino associated with reactions involving muons (one of the three known types of neutrino); also called mu-neutrino.
A neutrino of the type associated with the tau particle
A type or flavour of neutrino associated with reactions involving electrons (one of the three known types of neutrino).
A neutrino which is a Majorana particle.
The branch of astronomy concerned with the detection, observation, and interpretation of neutrinos reaching the earth from space.
A device for detecting and measuring neutrinos reaching the earth from space.
A unit used in expressing the detected flux of neutrinos from the sun, equal to 10−36 neutrino captures per target atom per second
