摘要：

We investigate resonance structures in CPT and Lorentz symmetry-violating neutrino-antineutrino oscillations in a two generation framework. The neutrino-antineutrino oscillations are induced by Lorentz- and CPT-violating terms in the Hamiltonian. The resonances are suitably described in terms of charge conjugation eigenstates of the system. The relations among the flavor, charge conjugation and mass eigenbasis of neutrino-antineutrino oscillations are examined along with the interplay between the available CPT-violating parameter space and possible resonance structures. Eventually we remark on the consequences of such scenarios for neutrino oscillation experiments, namely, possible solutions for the LSND and MiniBooNE anomalies.
