A neutrino (/ njuːˈtriːnoʊ / new-TREE-noh; denoted by the Greek letter ν) is an elementary particle that interacts via the weak interaction and gravity. [2][3] The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero.

Sep 7, 1999 · A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero.

Jul 13, 2022 · A neutrino is a subatomic particle and also an elementary or fundamental particle. In other words, it is smaller than an atom and does not consist of smaller subunits. It is a fermion, which is a particle with a spin of 1/2. The symbol for a neutrino is Greek letter nu (ν).

Jan 8, 2025 · Neutrino, elementary subatomic particle with no electric charge, very little mass, and 12 unit of spin. Neutrinos belong to the family of particles called leptons, which are not subject to the strong force.

Sep 21, 2022 · Neutrinos are tiny subatomic particles, often called 'ghost particles' because they barely interact with anything else. Neutrinos are, however, the most common particle in the universe. Believe...

The neutrino is perhaps the best-named particle in the Standard Model of Particle Physics: it is tiny, neutral, and weighs so little that no one has been able to measure its mass. Neutrinos are the most abundant particles that have mass in the universe.

Jan 25, 2011 · Neutrinos are teeny, tiny, nearly massless particles that travel at near lightspeeds. Born from violent astrophysical events like exploding stars and gamma ray bursts, they are fantastically...
