Nov 8, 2011 at 0:58 comment added David Z @Ben: hm, you might be right that this is a duplicate, but my intent here was to trace the evolution of this line of research after Chodos' papers up to just before the OPERA results, to get a sense of what stance became accepted by the scientific community and when. I'm looking for more detail than the other question which just asks "is it possible?" At least none of the answers to the other question seem to contain quite the kind of information I'm looking for.
Nov 8, 2011 at 0:07 comment added user4552 @leftaroundabout: There are two main types of models that have been proposed to explain this: (1) models in which neutrinos are tachyons and there is no Lorentz violation, and (2) models in which neutrinos are not tachyons and there is a preferred frame. You are correct that the SN1987A data contradict #1. In any case, we will probably have a result later this year from the improved experiment that will show that the original result was wrong. Ron: Please give us a reference. I don't think you know what you're talking about.
Nov 8, 2011 at 0:01 comment added user4552 This is a duplicate of this question: physics.stackexchange.com/questions/14968/… . I gave an answer there two days ago which I believe is up to date.
Oct 1, 2011 at 16:15 comment added Ron Maimon @leftaroundabout: This is the correct naive impression, but it is expanding around an unstable vacuum. A relativistic tachyonic neutrino doesn't travel faster than light, it just condenses to make a Lorentz violating vacuum.

Sep 23, 2011 at 16:11 comment added David Z Yeah, I had the same thought. But then again I wonder how these papers were published in the first place, if it were that easy.
Sep 23, 2011 at 16:09 comment added leftaroundabout One problem I see with this is that lower-energy neutrinos would exceed the speed of light more greatly than the high energy ones measured by OPERA, but for low-energy neutrinos we have a more strict bound thanks to the supernova measurements if I got this right.
