Solutions to the Atmospheric Neutrino Problem

Abstract

I summarize here the results of a global fit to the full data set corresponding to 535 days of data of the Super-Kamiokande experiment as well as to all other atmosferic neutrino experiments in order to compare the most likely solutions to the atmospheric neutrino anomaly in terms of oscillations in the $ν_μ\to ν_e$, $ν_μ\to ν_τ$, and $ν_μ\to ν_s$ channels.
