thread_title: Results?

message: A friend of mine quoted this article: http://arxiv.org/pdf/0706.0437v3 as saying that "The Minos neutrino experiment (completely independent) found an estimate of
(v − c)/c = 5.1 ± 1.2 (statistical) ± 2.6 (systematic) × 10**−5
where statistical and systematic are their estimates of these two different types of errors." - that neutrinos go *very slightly* faster than light.
I'm not physicist enough to tease this information out of the cited article, but given the recent CERN announcement, this might be worth considering for inclusion in this article. --Alvestrand (talk) 07:14, 23 September 2011 (UTC)
thread_title:  early indications that neutrinos travel faster than light? 

message: This article says The far detector has been fully operational since summer 2003, and has been taking cosmic ray and atmospheric neutrino data since early in its construction. The neutrino data is discussed, but nothing is said about the cosmic ray data. Please add something about the cosmic ray data.  --DThomsen8 (talk) 00:24, 9 January 2012 (UTC)

thread_title:  Cosmic rays 

message: MINOS reports a 15 ns difference (+/-30) in arrival times. That information (by itself) is totally NOT useful in comparing speeds. The same "information" is repeated in the Neutrino article, and in the Measuring Neutrino Speed article. Here is a calculation:  d=735 km. c = 299792 km/s;  t = d÷c = 0.00245 s;  Δt = 15e-9 sec; Δt/t = 6e-6 = 0.0006%. The difference between the two speeds is about 0.0006% plus or minus 0.0012%. You see, there is a difference between data and information. I am making the change to all 3 articles (I didn't check for its existence in other articles.) If I had more time, I'd also edit the blurb about "Further experiments, since MINOS made its last measurements over a month BEFORE this result was published. (And unless neutrinos do go back in time (are supraluminal) it isn't too likely that more measurements are going to be made. Perhaps more data is going to be analyzed?) While I'm at it I'd also suggest an edit of the horrible paragraph which discusses results at 68% Confidence. What kind of silliness was that?? It implies that a result can't be "consistent" with two different hypotheses and then explains that yes, it can. Wow. I like the use of "central value" but the rest is pretty poor. The result's central value was slightly faster than c, but the difference between the neutrinos speed and c was not significant at the 99% confidence level. And rather than "corrected" (implying an error was made to those who don't understand that "corrected" means "adjusted" or "refined") I'd suggest that "refined" be used: "After the detectors for the project were upgraded in 2012, MINOS corrected their initial result..." to "After the detectors for the project were upgraded in 2012, MINOS refined their initial result..." and remove "Further measurements are going to be conducted." 216.96.77.125 (talk) 16:31, 1 September 2015 (UTC)
