CPT violating neutrinos in the light of KamLAND

The KamLAND collaboration has observed a medium baseline oscillation signal for reactor antineutrinos. We show that a hierarchical CPT violating neutrino spectrum can simultaneously accommodate the oscillation data from LSND, atmospheric, solar and KamLAND, as well as the nonobservation of antineutrino disappearance in short baseline reactor experiments. In our scenario the KamLAND experiment is not observing an LMA solar oscillation signal. Instead the KamLAND oscillation signal is due to an independent mass splitting in the antineutrino spectrum. A larger antineutrino mass splitting accounts for the LSND signal and also contributes to atmospheric oscillations.
