The Search for Neutrino-Antineutrino Mixing Resulting from Lorentz Invariance Violation using neutrino interactions in MINOS

Understand

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-antineutrino 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-antineutrino mixing coefficients.
