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.
