Particle Physics any of three stable leptons having a mass approaching zero and no charge: a neutrino has almost no interaction with matter
Origin of neutrinoIt, coined by Enrico Fermi ; from neutrone (; from neutron) + diminutive suffix -ino
Any of three electrically neutral leptons (the electron neutrino, muon neutrino and tau neutrino—one in each of the three generations of elementary fermions) that have small or very small masses.
Origin of neutrinoItalian, from neutrino, little neutral one : neutro, neuter, neutral (from Latin neuter, neutr-, neuter; see neuter) + -ino, dimutive suff. (from Latin -&imacron;nus, adj. suff.; see –ine1). Coined by Enrico Fermi on the model of Italian neutrone, neutron, taken as the augmentative of Italian neutro.
- electron neutrino
- muon neutrino
- tau neutrino
- neutrino oscillation
- solar neutrino
From Italian neutrino (coined by Enrico Fermi), diminutive of neutro (“neutral").
