The superluminal propagation of neutrinos observed by OPERA collaboration can be interpreted as neutrinos traveling in a pseudoscalar potential which may be generated by a medium. The OPERA differential arrival time data set a constraint on…

We argue that the result quoted by the OPERA Collaboration cannot be interpreted as simply related to the muon neutrino moving at a superluminal velocity from the point of creation at CERN to the point of interaction at LNGS.
The OPERA experiment has been designed to perform the first detection of neutrino oscillations in direct appearance mode in the $\nu_{\mu}\to\nu_{\tau}$ channel, through the detection of the tau lepton produced in charged current…
