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 …

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 …

Dec 6, 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 …

Physicist Enrico Fermi popularized the name “neutrino”, which is Italian for “little neutral one.” Neutrinos are denoted by the Greek symbol ν, or nu (pronounced “new”). But not all neutrinos …

2 days ago · Neutrinos may be nearly invisible, but they play a starring role in the Universe. Long-standing anomalies had hinted at a mysterious fourth “sterile” neutrino, potentially rewriting the …

Neutrinos are neutral and extremely light subatomic particles, which weakly interact with matter. For this reason, detecting them is a very complex experimental challenge. Wolfgang Pauli …

Some elementary particles, such as the electron, are relatively well understood, while others, such as the elusive neutrino, present the physics community with many unanswered questions.

Apr 2, 2025 · Neutrinos are elementary particles that belong to the family of leptons, which also includes electrons, muons, and taus. Unlike other particles, neutrinos have no electric charge …

Enrico Fermi called the particle a neutrino and developed a theory of beta decay based on it, but it was not experimentally observed until 1956. This elusive particle, with no charge and almost …
