Explaining LSND and MiniBooNE using altered neutrino dispersion relations

We investigate the possibility of explaining the MiniBooNE anomaly using CPT-and Lorentz-symmetry-violating neutrino–antineutrino oscillations in a two-generation framework. We work with four non-zero CPT-violating parameters that allow for resonant enhancements in neutrino–antineutrino oscillation phenomena in vacuo which are suitably described in terms of charge conjugation eigenstates of the system. We study the relations among the flavor, charge conjugation and mass eigenbases of neutrino–antineutrino oscillations and examine the interplay between the available CPT-violating parameter space and possible resonance structures.
