(Spoiler: no, neutrinos ain’t faster than light!)
Abstract
We have measured the speed of muon neutrinos with the Borexino detector using short-bunch CNGS beams. The final result for the difference in time-of-flight between an 〈E〉= 17 GeV muon neutrino and a particle moving at the speed of light in vacuum is δt = 0.8 (±0.7 stat ±2.9 sys) ns, well consistent with zero.
