Abstract
We consider the consequences for future neutrino factory experiments of small CPT-odd interactions in neutrino oscillations. The \nu_\mu\to\nu_\mu and \bar\nu_\mu\to\bar\nu_\mu survival 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.
