particle physics - What happened to the idea of tachyonic or other superluminal neutrinos?


While hunting around for information about the recent OPERA measurement that hints at superluminal neutrinos, I discovered that this idea was actually considered back in the 1980s. Wikipedia lists as references two papers by Chodos et al. (unfortunately they're paywalled so I can't access them right now), and some more recent ones dealing with the Standard Model Extension.


I'm curious: what happened to this line of inquiry? Did it get conclusively disproven at some point, or just ignored because there was never any reason to believe that tachyons exist? Or are there still people doing legitimate research on it?
