Confirmation of oscillation evidence by MACRO and Soudan 2

Analysis of three-flavor oscillation and tau neutrino appearance

Abstract

In this talk, I will present a snapshot of key results regarding atmospheric neutrinos, as of the summer of 2002. I will review the evidence for neutrino oscillation, dominated by the large sample from Super-Kamiokande, but supported by confirmation from MACRO and Soudan 2. I will then review some of the more detailed inquiries made using Super-Kamiokande data such as alternative scenarios, three-flavor oscillation, and tau neutrino appearance.
