Can Neutrinos be Superluminal? Ask OPERA!

Abstract

Four days ago a rumour started circulating in the comments at Resonaances that some “6.1 sigma” signal of new physics had been seen at CERN. I reported it in an update on the Seminar Watch post. There had been a seminar titled “Seminar DG” which was listed on indico and removed the day before it was due. The rumour confirmed that this meeting was rescheduled to Friday but as an update on OPERA, the neutrino experiment which a couple of years ago saw its first tau neutrino. The claim now is that they have measured the speed of muon neutrinos and got a result faster than the speed of light!
