| dc.description | We present an analysis of the global neutrino oscillation data including the LSND result in terms of four-neutrino mass schemes and a CPT violating three-neutrino framework. We find that the strong preference of oscillations into active neutrinos implied by recent solar+KamLAND as well as atmospheric neutrino data allows to rule out (2+2) mass schemes at 5.8$σ$, whereas (3+1) schemes are disfavoured at the 3.2$σ$ level by short-baseline experiments. The CPT violating scenario is disfavoured at 3.4$σ$ by KamLAND and atmospheric anti-neutrino data. We conclude that currently no convincing explanation for the LSND signal exists, and it remains a puzzle how to reconcile it with the other evidences for neutrino oscillations. | |
