The neutrino puzzle in the light of SNO

SNO's neutral current measurement has added a new piece to the emerging neutrino physics puzzle. Putting together the presently available experimental information, an essentially unique picture emerges: The solar neutrino anomaly is explained by ν e → ν τ oscillations, the atmospheric neu-trino anomaly is explained by ν µ → ν s and the LSND data are explained by ν e → ν µ. This scheme will be tested by future experiments: MiniBooNE will test the oscillation explanation of the LSND anomaly, while the long baseline experiments will discriminate between the ν µ → ν s and ν µ → ν τ possibilities for resolving the atmospheric anomaly (confirming or disconfirming the Super-Kamiokande result that the latter is favoured over the former).
