Four neutrino oscillation analysis of atmospheric neutrino data and application to long baseline experiments

Abstract

Analyis of the Superkamiokande atmospheric neutrino data is presented in the framework of four neutrinos without imposing constraints of Big Bang Nucleosynthesis. Implications to long baseline experiments are briefly discussed.
