The Discovery of the Atmospheric Neutrino Anomaly

Abstract

The discovery of the missing atmospheric muon neutrinos known as the atmospheric neutrino anomaly, is briefly described. Learned and Lipari gave a general review of atmospheric neutrinos at the conference, including the discovery of the anomaly by IMB-1 and subsequent work. Questions answered in this brief note include: the cautious wording, the statistical significance, the 1992 eronious exclusion plot, the Kamiokande confirmation and SuperK's failure to cite the original 1986 IMB-1 discovery.
