neutrino

 [noo-tre´no]
a subatomic particle with an extremely small mass and no electric charge.

neutrino

(nū-trē′nō)
In physics, a subatomic particle at rest, with no mass and no electric charge. These particles are constantly flowing through the universe and are not known to affect the matter through which they pass.

neutrino

a subatomic particle with an extremely small mass (theoretically zero rest mass) and no electric charge.

Because of these wave interactions, a neutrino that starts as an electron neutrino, for example, can have a four-ninths probability of showing up as a different flavor somewhere down the line.
The ground state up and antiup quark pair completely annihilates into an electron neutrino, [u.
Unlike the ordinary-water detectors, which are sensitive only to electron neutrinos, Sudbury's heavy water will be sensitive to all three types of neutrinos, because they can knock the neutron from a deuterium nucleus to produce a different light signal.
Periodic oscillations have been reported [24] in Pm142 which show an oscillating sinusoidal decay for electron capture (as contrasted to a conventionally established exponential decay) which the authors attribute to modulations caused by the oscillation of neutrinos between two different mass states (flavors), that of the electron neutrino emitted in the original decay, and that of the muon neutrino which is observed in decays of the muon (a particle 200 times more massive than the electron).
But the new data indicate that electron neutrinos oscillate with other flavors as they make their way to Earth.
The Los Alamos researchers used an accelerator to fire neutrinos into a tank of mineral oil, finding that muon neutrinos changed into electron neutrinos en route.
Pions decay into muons and muon neutrinos, and the muons, in turn, transform into positrons, electron neutrinos, and muon antineutrinos.
The W can then decay into a lighter quark and an antiquark or into a pair of leptons (an electron and electron neutrino or a muon and muon neutrino).
These pions decay into muons, muon neutrinos, muon antineutrinos, and electron neutrinos, but not electron antineutrinos.
As Ralston told SCIENCE NEWS, the particles of physics can be divided into three separate generations, exemplified by the electron and the electron neutrino, the muon and the muon neutrino, and the tau particle and the tau neutrino.
And the first dataset from T2K shows it detected 32 electron neutrinos and only 4 electron antineutrinos, indicating there is more physics beyond the Standard Model.
Washington, June 25 (ANI): Ten days ago Japanese scientists announced an indication of a rare phenomenon, the transformation of muon neutrinos into electron neutrinos.
