Direct Observation of NU Tau
Although it is Fermi dated(last modified 07/09/2000) it is good to see parts of this progression in LHC? Does Tau Neutrino have it’s roots in other places as well? So sometimes it is nice to see this connection for myself. Creating a Tau Neutrino Beam (link) See Also: Direct Observation of NU Tau Dialogos of…

first tau-neutrino “appearing” out of several billion of billions muon neutrinos
Layout of the CNGS beam line. The OPERA neutrino experiment [1] at the underground Gran Sasso Laboratory (LNGS) was designed to perform the first detection of neutrino oscillations in direct appearance mode in the νμ→ντ channel, the signature being the identification of the τ− lepton created by its charged current (CC) interaction [2]. See: Measurement…

Energy Boost From Shock Front
Main Components of CNGS A 400 GeV/c proton beam is extracted from the SPS in 10.5 microsecond short pulses of 2.4×1013 protons per pulse. The proton beam is transported through the transfer line TT41 to the CNGS target T40. The target consists of a series of graphite rods, which are cooled by a recirculated helium…

In regards to Cherenkov Light Thinking outside the box See: A physicist inthe cancer lab Ackerman became interested in physics in middle school, reading popular science books about quantum mechanics and string theory. As an undergraduate at the Massachusetts Institute of Technology, she traveled to CERN, the European particle physics laboratory near Geneva, to work…

Seeing Underlying Structures
There is gap between, “Proton Collision ->Decay to Muons and Muon Neutrinos ->Tau Neutrino ->[gap] tau lepton may travel some tens of microns before decaying back into neutrino and charged tracks.” Use the case of Relativistic Muons? An analysis of four Fermi-detected gamma-ray bursts (GRBs) is given that sets upper limits on the energy dependence…

Cohen-Glashow Argument
Bee:And for all I know you need a charge for Cherenkov radiation and neutrinos don’t have one. Fig. 1: Cerenkov radiation involves the nearly continuous emission of photons by a charged particle moving faster than the speed of light in its vicinity. The charged particle gradually radiates away its energy. Cohen-Glashow emission involves the occasional…

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…

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…

Latest News At Cern
What’s new @CERN ? a new video programme launched on webcast.cern.ch , every first Monday of the Month. For the first one, the themes are the results of the LHC experiments about Higgs boson, standard model and supersymmetry, and also neutrinos of OPERA experiment faster than the speed of light. Thanks Lubos STANDARD MODEL OF…

Measurement of the neutrino velocity with the OPERA detector in the CNGS beam
We know already why the neutrinos could go faster and what new experiments this suggests, why it does not imply time travel or violates causality, and why it is somewhat expected for neutrinos. Now let us focus on what kind of superluminal velocity is indicated.See:A Million Times The Speed Of Light Measurement of the neutrino…
