Abstract
The measurement of the neutrino velocity with the OPERA detector in the CNGS beam shows unexpected indication, that the muon neutrino velocity, vν, exceeds the velocity of light in the vacuum, c, which is obviously in contradiction with the most basic hypothesis of modern physics. Within the framework of minimal Standard Model Extension (SME), we discuss the modified dispersion relation and consequently the velocity–energy relation of muon neutrinos. The simplified models are fitted to the OPERA data, Fermilab experiment and MINOS data. We find that minimal Standard Model Extension can describe these long baseline superluminal neutrinos to a good accuracy. For the well-known tension between the OPERA measurement and the Supernova 1987A neutrino observation, we discuss two ways out of the contradiction.
