Query: Neutrinos as the messengers of CPT violation   CPT violation has the potential to explain all three existing neutrino
anomalies without enlarging the neutrino sector. CPT violation in the Dirac
mass terms of the three neutrino flavors preserves Lorentz invariance, but
generates independent masses for neutrinos and antineutrinos. This specific
signature is strongly motivated by braneworld scenarios with extra dimensions,
where neutrinos are the natural messengers for Standard Model physics of CPT
violation in the bulk. A simple model of maximal CPT violation is sufficient to
explain the exisiting neutrino data quite neatly, while making dramatic
predictions for the upcoming KamLAND and MiniBooNE experiments. Furthermore we
obtain a promising new mechanism for baryogenesis.
