1. neutrinonoun

   An elementary particle that is classified as a lepton, and has an extremely small but nonzero mass and no electric charge. It interacts with the surroundings only via the weak force or gravitation, making it very difficult to detect.

2. Etymology: From neutrino (coined by), diminutive of neutro.

1. Neutrino

   A neutrino ( new-TREE-noh; denoted by the Greek letter ν) is a fermion (an elementary particle with spin of 1/2) that interacts only via the weak interaction and gravity. 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. The rest mass of the neutrino is much smaller than that of the other known elementary particles excluding massless particles. The weak force has a very short range, the gravitational interaction is extremely weak due to the very small mass of the neutrino, and neutrinos do not participate in the strong interaction. Thus, neutrinos typically pass through normal matter unimpeded and undetected.Weak interactions create neutrinos in one of three leptonic flavors: electron neutrinos (νe), muon neutrinos (νμ), or tau neutrinos (ντ), in association with the corresponding charged lepton. Although neutrinos were long believed to be massless, it is now known that there are three discrete neutrino masses with different tiny values (the smallest of which may even be zero), but the three masses do not uniquely correspond to the three flavors. A neutrino created with a specific flavor is a specific mixture of all three mass states (a quantum superposition). Similar to some other neutral particles, neutrinos oscillate between different flavors in flight as a consequence. For example, an electron neutrino produced in a beta decay reaction may interact in a distant detector as a muon or tau neutrino. The three mass values are not yet known as of 2022, but laboratory experiments and cosmological observations have determined the differences of their squares, an upper limit on their sum (< 2.14×10−37 kg), and an upper limit on the mass of the electron neutrino.

1. neutrino

   A neutrino is an elementary particle in the lepton family, one of the fundamental particles that make up the universe. Neutrinos are neutral (no electric charge), have an extremely small mass which may even be zero, and interact only weakly with other matter, making them difficult to detect. They come in three types or "flavours" – electron neutrinos, muon neutrinos, and tau neutrinos. Neutrinos are produced in various natural and artificial processes, such as nuclear reactions in the sun and other stars, radioactive decay, and during particle collisions in accelerators.

1. Neutrino

   A neutrino is an electrically neutral, weakly interacting elementary subatomic particle with half-integer spin. The neutrino is denoted by the Greek letter ν. All evidence suggests that neutrinos have mass but that their mass is tiny even by the standards of subatomic particles. Their mass has never been measured accurately. Neutrinos do not carry electric charge, which means that they are not affected by the electromagnetic forces that act on charged particles such as electrons and protons. Neutrinos are affected only by the weak sub-atomic force, of much shorter range than electromagnetism, and gravity, which is relatively weak on the subatomic scale. Therefore a typical neutrino passes through normal matter unimpeded. Neutrinos are created as a result of certain types of radioactive decay, or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms. There are three types, or "flavors", of neutrinos: electron neutrinos, muon neutrinos and tau neutrinos. Each type is associated with an antiparticle, called an "antineutrino", which also has neutral electric charge and half-integer spin. Whether or not the neutrino and its corresponding antineutrino are identical particles has not yet been resolved, even though the antineutrino has an opposite chirality to the neutrino.10

Examples of neutrino in a Sentence

1. Doug Cowen:

   This identification launches the new field of high-energy neutrino astronomy, which we expect will yield exciting breakthroughs in our understanding of the universe and fundamental physics, including how and where these ultra-high-energy particles are produced, for 20 years, one of our dreams as a collaboration was to identify the sources of high-energy cosmic neutrinos, and it looks like we've finally done it !

2. Phil Evans:

   We continue to search for counterparts to neutrino detections, to understand whether all such events come from blazars like this one, or whether there is a diversity of celestial objects can produce such highly energetic neutrinos.

3. Elisa Resconi:

   If the characterization of the site proves to be excellent, one could consider how a full-scale neutrino observatory might be deployed on a relatively fast timescale thanks to the existing deep-water infrastructure, a neutrino detector array operated in the Pacific would ideally complement IceCube and its second generation at South Pole.
