The search for neutrino-antineutrino mixing resulting from Lorentz invariance violation using neutrino interactions in MINOS

We searched for a sidereal modulation in the rate of neutrinos produced by the NuMI beam and observed by the MINOS far detector. The detection of such harmonic signals could be a signature of neutrino-anti-neutrino mixing due to Lorentz and CPT violation as described by the Standard-Model Extension framework. We found no evidence for these sidereal signals and we placed limits on the coefficients in this theory describing the effect. This is the first report of limits on these neutrino-anti-neutrino mixing coefficients. (c) 2013 Elsevier B.V. All rights reserved.
