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.

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.

Mar 1, 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.

A neutrino is a particle! It’s one of the so-called fundamental particles, which means it isn’t made of any smaller pieces, at least that we know of. Neutrinos are members of the same group as the most famous fundamental particle, the electron (which is …

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...

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).

3 days ago · Other experiments will also contribute to a better understanding of the neutrino’s mass, including Project 8 in Seattle and the Deep Underground Neutrino Experiment, spread across two physics ...

Neutrinos are among the most abundant particles in the universe, a billion times more abundant than the particles that make up stars, planets and people. Unimaginably large numbers of neutrinos from the first moments of the universe are still present today.

3 days ago · The most advanced attempt yet to weigh neutrinos has put a new upper limit on the enigmatic particle’s mass. It is no heavier than 0.45 electron volts (eV) — less than one-millionth the mass ...
