Status of the CPT violating interpretations of the LSND signal

We study the status of the CPT violating neutrino mass spectrum which has been proposed to simultaneously accommodate the oscillation data from LSND, KamLAND, atmospheric and solar neutrino experiments, as well as the nonobservation of the antineutrino disappearance in short-baseline reactor experim...
