Physicists searching for a hypothetical and rare process involving radioactive decay of atomic nuclei have gotten their most sensitive results to date, suggesting that these mysterious particles behave like other elementary particles at the quantum level. If such a discovery can be made, the researchers said the process could have profound implications for how scientists understand the fundamental laws of physics and could help solve some of the biggest mysteries of the universe. The...

Daya Bay Scientists Observe Previously Unseen Neutrino Transformation

An international team of physicists collaborating on a neutrino experiment that began six years ago released their first results on Thursday, and they report that for the first time they have witnessed an elusive process in which one type of these subatomic particles transforms into another. The findings originate from the Daya Bay Reactor Neutrino Experiment, the first equal collaboration between scientists from the US and China which began in 2006 and has since gained financial,...

An international particle physics collaboration today announced its first results toward answering a longstanding question — how the elusive particles called neutrinos can appear to vanish as they travel through space. The result from the Daya Bay Reactor Neutrino Experiment [link: http://dayawane.ihep.ac.cn/] describes a critical and previously unmeasured quality of neutrinos — and their antiparticles, antineutrinos — that may underlie basic properties of matter and...

They were always mysterious. 26 years had to pass before the prediction of theoretical physics was confirmed and the existence of neutrinos was finally proven experimentally in 1956. The reason for this ordeal: Neutrinos only interact by the weak interaction with other particles of matter. When a cosmic neutrino approaches the earth, it has the best chance of passing through the whole globe unhindered. It is correspondingly difficult to find direct evidence of neutrinos with the help of a...

A new Chinese experiment could help explain why matter predominates over antimatter in the universe. The Daya Bay experiment aims to explain the mystery by using antineutrinos as a probe to measure a crucial type of transformation called neutrino mixing. "Right now there is not a good understanding of what causes the matter-antimatter imbalance in the universe," Karsten Heeger, a University of Wisconsin"“Madison physics professor and one of the leading scientists in the experiment,...

The results of a high-profile Fermilab physics experiment involving a University of Michigan professor appear to confirm strange 20-year-old findings that poke holes in the standard model, suggesting the existence of a new elementary particle: a fourth flavor of neutrino. The new results go further to describe a violation of a fundamental symmetry of the universe asserting that particles of antimatter behave in the same way as their matter counterparts. Neutrinos are neutral elementary...

An international team including scientists from Princeton University has detected subatomic particles deep within the Earth's interior. The discovery could help geologists understand how reactions taking place in the planet's interior affect events on the surface such as earthquakes and volcanoes. Someday, scientists may know enough about the sources and flow of heat in the Earth to predict events like the recent volcanic eruption in Iceland. The finding, made by the Borexino Collaboration at...

Scientists of the MINOS experiment at the Department of Energy's Fermi National Accelerator laboratory today (June 14) announced the world's most precise measurement to date of the parameters that govern antineutrino oscillations, the back-and-forth transformations of antineutrinos from one type to another. This result provides information about the difference in mass between different antineutrino types. The measurement showed an unexpected variance in the values for neutrinos and...

Will the universe expand outward for all of eternity and end in a vast, dark, cold, sterile, diffuse nothingness? Or will the "Big Bang" "” the gargantuan explosion that formed the universe 14 billion years ago "” end in the "Big Crunch?" Planets, stars and galaxies all hurtle inward and collapse into an incredibly hot, dense mass a billion times smaller than the period at the end of this sentence. And then "¦ KA-BOOOOM!!! Another Big Bang and another universe forms and...

International inspectors may have a new tool in the form of an antineutrino detector that could help them peer inside a working nuclear reactor. A Lawrence Livermore National Laboratory-Sandia National Laboratories' team recently demonstrated that the operational status and thermal power of reactors can be quickly and precisely monitored over hour-to month-time scales, using a cubic-meter-scale antineutrino detector.Adam Bernstein, leader of the Advanced Detectors Group at LLNL, is the...
