| This approach is already used to detect neutrinos, which have similarly weak interactions with matter. |
|
| Solar neutrinos are produced when two protons fuse together to form a deuterium nucleus, a positron, and a neutrino. |
|
| This colour quantum number is additional to leptonic flavour which distinguishes neutrinos from charged leptons. |
|
| At the same time, particles such as cosmic rays and neutrinos began to be gathered from space. |
|
| When neutrinos passing through the heavy water interact with deuterium nuclei, flashes of light, called Cerenkov radiation, are emitted. |
|
| The failure to blow up suggests that physicists are missing something essential about neutrinos and nuclear physics, says Janka. |
|
| Quarks have bosonic partners called squarks, neutrinos have sneutrinos and so on. |
|
| Cosmic neutrinos are extremely high energy subatomic particles, like protons and electrons, but neutrinos have no electrical charge. |
|
| When massive stars die, most of their energy is released as neutrinos in violent supernova explosions. |
|
| The electron and muon neutrinos are easier to produce and detect than the tau neutrino. |
|
| The core of the exploding star was converted to neutrons during the explosion when protons and electrons were forced together in reverse beta decay, producing the neutrinos. |
|
| Not far from Hong Kong, along Daya Bay, researchers are studying neutrinos spit from six nuclear reactors. |
|
| Rudolf Peierls and Hans Bethe calculated that neutrinos could easily pass through the Earth, so the chances of detecting them were slim. |
|
| Such oscillations would become analogous to those of neutrinos which have nonzero rest masses. |
|
| That result also requires a mass difference between neutrinos and antineutrinos, Mohapatra says, though others disagree. |
|
| The scientists had predicted there would be such a deficit if muon neutrinos became tau neutrinos. |
|
| Therefore, the additional neutrino flow detected at Super-Kamiokande must be made of up muon and tau neutrinos. |
|
| Cowsik suggests that electron and tau neutrinos may be mixing together in this case. |
|
| They discovered 26 more high-energy events, all at levels of 30 teraelectronvolts or higher, indicative of astrophysical neutrinos. |
|
| As the pions traveled away from the target they disintegrated into mu-mesons and neutrinos. |
|
|
|
| To date, we've got bosons, fermions, leptons, muons, pions, neutrinos, photons, gluons, and gravitons. |
|
| For two years, IceCube scientists watched for neutrinos after gamma-ray bursts, focusing on the muon neutrino subtype. |
|
| Sterile neutrinos are a hypothetical type of neutrino that is predicted to interact with normal matter only via gravity. |
|
| McDonald in Canada, for their key contributions to the experiments which demonstrated that neutrinos change identities. |
|
| The ghostly realm of string theory, fermions, neutrinos and quarks was not even in the scope of theory. |
|
| The OPERA neutrinos had energies of about 17 gigaelectron volts. |
|
| These stellar explosions send fundamental, uncharged particles called neutrinos streaming our way and generate ripples called gravitational waves in the fabric of space-time. |
|
| The most likely explanation, physicists say, is that muon neutrinos, the type produced on high, were changing into tau neutrinos, which the detector can't pick up. |
|
| Two of the neutrinos had an energy of more than 1,000 TeV-that's more than the kinetic energy of a fly in flight-compressed into a single elementary particle. |
|
| One intriguing possibility is that the X-rays are produced by the decay of sterile neutrinos, a type of particle that has been proposed as a candidate for dark matter. |
|
| Along with the electron and muon, the tau particle and three varieties of neutrinos are now firmly established as members of the lepton group of subatomic particles. |
|
| They say that the dark matter has scattered due to the gravitational force and an interaction with the photons and neutrinos in the young universe. |
|
| In past experiments, physicists have measured the change of muon neutrinos to tau neutrinos and electron neutrinos to muon neutrinos or tau neutrinos. |
|
| But researchers at the CERN lab near Geneva claim they have recorded neutrinos, a type of tiny particle, travelling faster than the barrier of 186,282 miles per second. |
|
| A total of 15,000 beams of neutrinos were fired over a period of 3 years from CERN towards Gran Sassoin Italy, 730km away, where they were picked up by giant detectors. |
|
| Neutrinos bouncing off of electrons would also produce Cherenkov radiation at lower energies, so Koshiba modified the design. |
|
| Neutrinos are ghostly particles that can travel through a light year of lead and they have no problem escaping directly from the core of a supernova. |
|
| Neutrinos are minuscule particles created in nuclear reactions, such as in the sun and the stars, or in nuclear power plants. |
|
| Neutrinos and muons are leptons and so are believed to be simple elementary particles. |
|
| Neutrinos from the supernova 1987a were detected by the Kamioka Nucleon Decay Experiment detector in Japan. |
|
|
|
| Neutrinos only interact via the weak nuclear force, which has very short range, points out Boris Kayser, a neutrino theorist at Fermilab. |
