An elementary particle produced by certain nuclear decay processes. Neutrinos have no charge and extremely small masses compared to other subatomic particles.

Group of electrically neutral elementary particles with a mass of almost zero.

"neutral particle smaller than a neutron," 1934, from Italian neutrino, coined 1933 by Italian physicist Enrico Fermi (1901-1954) from neutro "neuter" (see neuter (adj.)) + -ino, d [..]

A fundamental particle produced by the nuclear reactions in stars. Neutrinos are very hard to detect because the vast majority of them pass completely through the Earth without interacting.

subatomic particle that carries no electrical charge and interacts weakly with all other matter.

A fundamental particle which has no electric charge and hardly interacts with matter. Thus it is very elusive and difficult to detect. Neutrinos only have a small mass but they are very numerous and may account for some of the dark matter in the Universe. The existence of the neutrino was postulated by Enrico Fermi to explain a loss of energy in th [..]

A fundamental particle. A neutral lepton, there are three, one each associated with the elesctron, muon and tau particles. The mass of neutrinos is thought to be either extremely small or zero. The interact extremely weakly with normal matter. They are produced in fusion reactions in stellar interiors. The first detection of neutrinos associated wi [..]

An electrically neutral particle with negligible mass. It is produced in many nuclear reactions such as in beta decay.

an uncharged, weakly interacting lepton, most commonly produced in nuclear reactions such as those in the sun. There are three known flavors of neutrino, corresponding to the three flavors of leptons. Recent experimental results indicate that all neutrinos have tiny masses.

An uncharged, massless (or at least extremely light), lepton.Like the charged leptons, they can come in three types (or flavours):electron neutrinos, muon neutrinos,or tau neutrinos.

uncharged lepton with a very low rest mass compared with the electron

The neutrino is a particle with no mass or charge. It is emitted during Beta decay during the emission of a beta particle. It has no great significance with respect to Radiation Protection but great i [..]

(n) an elementary particle with zero charge and zero mass

A lepton with no electric charge. Neutrinos participate only in weak and gravitational interactions and are therefore very difficult to detect. There are three known types of neutrinos, all of which have very little mass.

Electrically neutral lepton; exists in three distinct flavors or varieties (Martin).

a subatomic particle produced in nuclear reactions and in supernovae that very rarely interacts with matter; neutrinos have no electrical charge and travel at or very close to the speed of light.

A neutral, weakly interacting elementary particle having a very tiny mass. Stars like the Sun produce more than 200 trillion trillion trillion neutrinos every second. Neutrinos from the Sun interact so weakly with other matter that they pass straight through the Earth as if it weren’t there.
