Latest Neutrinos Stories

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...

News from the American Physical Society Hydrodynamics of writing with ink Jungchul Kim, Myoung-Woon Moon, Kwang-Ryeol Lee, L. Mahadevan, and Ho-Young Kim Physical Review Letters (forthcoming) For millennia, writing has been the preferred way to convey information and knowledge from one generation to another. We first developed the ability to write on clay tablets with a point, and then settled on a reed pen, as preserved from 3000 BC in Egypt when it was used with papyrus. This...

Fast Than The Speed Of Light? Not So Fast Scientists Say
2011-11-21 09:22:37

Italian scientists who had seemingly found further evidence that neutrino particles were in fact traveling faster than the speed of light based on experiments have been dealt a major blow over the weekend by another team working at the Gran Sasso laboratory in Italy that claims the evidence must be flawed, according to a recent Reuters report. An announcement in September by a team of scientists working on the OPERA (Oscillation Project with Emulsion-tracking Apparatus) experiment claiming...

New Tests Confirm Neutrinos Are Still Faster Than Light
2011-11-18 12:36:05

Scientists who believed to have found in September that certain neutrinos travel faster than light have ruled out a potential source of error in their measurements after completing a second round of tests, further fracturing Einstein´s theory of relativity. The team´s results, posted on the ArXiv preprint server this morning, confirmed their earlier measurements that neutrinos, sent through the ground from CERN -- on the Swiss-French border -- to the Gran Sasso lab in Italy 450...

Relativity Corrections Could Explain Faster Than Light Neutrinos

When researchers at the European Center for Nuclear Research (CERN) observed what they believed to be sub-atomic particles moving faster than the speed of light, some believed that the discovery could challenge the very fundamental laws of the universe. It appears that those concerns were unfounded, as new research from scientists has shed light on exactly why CERN officials believe they witnessed beams of tiny particles of neutrinos traveling 60 nanoseconds (or 60 billionths of a second)...

Using one of the most sensitive neutrino detectors on the planet, an international team including physicists Laura Cadonati and Andrea Pocar at the University of Massachusetts Amherst are now measuring the flow of solar neutrinos reaching earth more precisely than ever before. The detector probes matter at the most fundamental level and provides a powerful tool for directly observing the sun´s composition. Pocar, Cadonati and colleagues report in the current issue of Physical Review...

Have CERN Experiments Broken The Speed Of Light?

  Researchers at the European Centre for Nuclear Research (CERN) are reporting that they have discovered sub-atomic particles moving faster than the speed of light -- a finding which, if verified, could well turn the fundamental laws of the universe on their ear. According to various media reports Thursday, the experiment responsible for the discovery involved sending 15,000 beams of tiny particles known as neutrinos from the CERN laboratory near Geneva, Switzerland to the Gran...

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,...

An international research team led by Japan and that includes the University of Colorado Boulder may have taken a significant step in discovering why matter trumped antimatter at the time of Big Bang, helping to create virtually all of the galaxies and stars in the universe. The experiment, known as the Tokai to Kamioka experiment, or T2K, included shooting a beam of neutrinos underground from the Japan Proton Accelerator Research Complex, or J-PARC, on the country's east coast to a detector...
