Measurement of the neutrino velocity with the OPERA detector in the CNGS beam — mentioned by Anon84

Let's hope they learned the "Faster than light neutrino" lesson... EDIT: In reply to comments: 1. The speed of the neutrino had already been measure experimentally before. It was unlikely that a new experiment would produce different results. 2. Requests for help from the scientific community are not delivered via press releases. Specially in an area as relatively small as high energy physics where everyone knows everyone. 3. If you look at the slides used to announce the "result" http://indico.cern.ch/getFile.py/access?resId=0&material... nowhere does it mention that they are not sure of the…

The original paper (http://arxiv.org/abs/1109.4897) had some 188 authors. I doubt they didn't double-check or 100-check the results. After some point the data just had to be considered believable or worthy of publication. You really think it would be better if they didn't let the world know about it?

While it may have been checked it doesn't seem to be mentioned in the paper http://arxiv.org/abs/1109.4897v2

I'm super-skeptical about this paper - I agree that more info on the GPS stuff is needed (this author seems to be making assumptions about how the correction procedures work that I couldn't find documentation for), but on its face, this just seems way like a way too obvious error to possibly be right. First off, I encourage everyone to read the actual paper at http://arxiv.org/pdf/1110.2685v1 [PDF], I think many here are seriously overestimating the complexity of the author's claim. I've mostly said this already on this thread, but it's buried near the bottom of the page, so I'll summarize…

I've read the article[1] and what they do is compare the proton flux as measured in Geneva with the neutrino signal measured in Gran Sasso. The proton signal is timeshifted a small amount until the curves overlap maximally. Where the leading and trailing edge are is irrelevant here, as the complete shape of the pulses are compared. 1: http://static.arxiv.org/pdf/1109.4897.pdf

My SWAG: the relativist effect of time being slowed down in Earth's gravity was not taken into account. (Time is slowed down, therefore neutrinos appear to arrive 60ns "early".) They spent a lot of time triple checking the accuracy of their instruments without seemingly thinking about higher level factors such as the Theory of relativity... http://static.arxiv.org/pdf/1109.4897.pdf Of course there are 99% chances I am wrong, but just throwing this out there :)

I so LOL'd when someone in the webinar pointed out that their measurement wasn't a vector so their paper should be titled neutrino speed not velocity. http://arxiv.org/abs/1109.4897
