CPT-odd Resonances in Neutrino Oscillations
V. Barger, S. Pakvasa, T. J. Weiler, K. Whisnant
Abstract
We consider the consequences for future neutrino factory experiments of small CPT-odd interactions in neutrino oscillations. The νμνμand νμνμsurvival probabilities at a baseline L=732 km can test for CPT-odd contributions at orders of magnitude better sensitivity than present limits. Interference between the CPT-violating interaction and CPT-even mass terms in the Lagrangian can lead to a resonant enhancement of the oscillation amplitude. For oscillations in matter, a simultaneous enhancement of both neutrino and antineutrino oscillation amplitudes is possible.
