Daya Bay
The Daya Bay site in southern China. Image: Lawrence Berkeley Laboratory An international collaboration of physicists working on a neutrino experiment in southern China announced today they have made a difficult measurement scientists have been chasing for more than a decade. The results of the Daya Bay neutrino experiment open an important window into understanding…

Proton Collision ->Decay to Muons and Muon Neutrinos ->Tau Neutrino ->
…..tau lepton may travel some tens of microns before decaying back into neutrino and charged tracks Before I comment on the result, let me give you a little background on the whole thing. Opera is a very innovative concept in neutrino detection. Its aim is to detect tau neutrino appearance in a beam of muon…

Cherenkov radiation
Taking the formalisms of electromagnetic radiation and supposing a tachyon had an electric charge—as there is no reason to suppose a priori that tachyons must be either neutral or charged—then a charged tachyon must lose energy as Cherenkov radiation[15]—just as ordinary charged particles do when they exceed the local speed of light in a medium.…

P.I. Chats: Faster-than-light neutrinos?
Measurements by GPS confirm that the neutrinos identified by the Super-Kamiokande detector were indeed produced on the east coast of Japan. The physicists therefore estimate that the results obtained point to a 99.3% probability that electron neutrino appearance was detected.Neutrino Oscillations Caught in the Act The Gran Sasso National Laboratory (LNGS) is one of four…

Linking Experiments
Illustration: Sandbox Studio The first round of physics Nine proposals are under consideration for the initial suite of physics experiments at DUSEL, and scientists have received $21 million in NSF funding to refine them. The proposals cover four areas of research: What is the nature of dark matter? (Proposals for LZ3, COUPP, GEODM, and…

Neutrinoless Double Beta Decay
“You don’t see what you’re seeing until you see it,” Dr. Thurston said, “but when you do see it, it lets you see many other things.Elusive Proof, Elusive Prover: A New Mathematical Mystery The Enriched Xenon Observatory is an experiment in particle physics aiming to detect “neutrino-less double beta decay” using large amounts of xenon…

Permanence of Fact in Literature
John Updike in 1955. John Hoyer Updike (18 March 1932 – 27 January 2009) was an American novelist, poet, short story writer, art critic, and literary critic. Updike’s most famous work is his Rabbit series (Rabbit, Run; Rabbit Redux; Rabbit Is Rich; Rabbit At Rest; and Rabbit Remembered). Both Rabbit is Rich and Rabbit at…

Galactic Neutrino Communications
Galactic Neutrino Communication by John G. Learned, Sandip Pakvasa, A. Zee We examine the possibility to employ neutrinos to communicate within the galaxy. We discuss various issues associated with transmission and reception, and suggest that the resonant neutrino energy near 6.3 PeV may be most appropriate. In one scheme we propose to make Z^o particles…

Geoneutrinos
Geoneutrinos, anti-electron neutrinos emanating from the earth, are expected to serve as a unique window into the interior of our planet, revealing information that is hidden from other probes. The left half of this image shows the production distribution for the geoneutrinos detected at KamLAND, and the right half shows the geologic structure. See First…

The CrossOver Point within the Perfect Fluid?
I had been following this research because of what I had been trying to understand when we take our understanding down to a certain level. That level is within the context of us probing the collision process for evidence of “some new physics” that we had not seen before. Evidence for Neutrino Oscillations from the…

Blackhole evaporation: What’s New From the Subatomic-Sized Holes ?
…the creative principle resides in mathematics. In a certain sense therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed.Albert Einstein See What is Cerenkov Radiation? We are being “politically correct” (a sociological observation) when we change the wording of the “microstate blackhole production” to “Sub Atomic Sized Holes?” To…
