Title: Tau appearance in atmospheric neutrino interactions

Abstract

If the correct interpretation of the Super-Kamiokande atmospheric neutrino data is {nu}{sub {mu}} {yields} {nu}{sub {tau}} oscillation, the contained data sample should already have more than 10 {tau} appearance events. We study the challenging task of detecting the {tau}, focusing on the decay chain {tau}{sup {+-}} {yields} {rho}{sup {+-}} {yields} {pi}{sup {+-}}{pi}{sup 0} in events with quasi-elastic {tau} production. The background level, which is currently quite uncertain because of a lack of relevant neutral current data, can be measured by the near detector in the K2K experiment. Our estimates of the background suggest that it may be possible to detect {tau} appearance in Super-Kamiokande with 5-10 years of running.
