Electrons and positrons have opposite electrical charges, but neutrinos and antineutrinos have no charge.
Neutrinos and antineutrinos are also notorious flip-floppers--one type constantly shifting into another.
Occasionally, however, an antineutrino from an underground decay collides with a molecule in the KamLAND tank, resulting in a signature written in light: two flashes in rapid succession.
The team, which includes Learned and 91 other physicists, is performing its experiment at a huge, underground detector known as the Kamioka Liquid Scintillator Antineutrino Detector, or KamLAND.
This proposal opens the possibility that two neutrons may decay so that the antineutrino emitted by one is promptly absorbed by the other.
Having a third antineutrino detector might enable researchers to map the distribution of uranium and thorium inside Earth, Raghavan notes.
In this case, the findings suggest that the muon antineutrino or the electron antineutrino has a mass of at least 0.
For example, when a cobalt-60 nucleus having a particular orientation decays to create a nickel-60 nucleus, an electron, and an antineutrino, the electron is ejected preferentially in one direction.
But the relevance of this measurement, which sets an upper limit of 8 electronvolts on the mass of an electron antineutrino, remains clouded by concerns that an unknown physical effect may be interfering with the experiment.
Spectral Measurement of Electron Antineutrino Oscillation Amplitude and Frequency at Daya Bay.
A new map flags which areas of the planet emit an abundance of these particles, marking antineutrino hot spots in red, Meghan Rosen wrote in "Map captures sources of Earth's antineutrino glow" (SN: 10/3/15, p.
58) A neutron will decay into a proton, an electron and an antineutrino over a relatively short time frame.
The inside of a cylindrical antineutrino detector before being filled with clear liquid scintillator, which reveals antineutrino interactions by the very faint flashes of light they emit.
