Bounds on ${\nu }_{\mu }$ Oscillations from Atmospheric Neutrinos

Abstract

A reanalysis of identified muon neutrino interactions from IMB 3 yields bounds on ${\sin }^2(2\theta )$ and $\Delta m^2$. The limit ${\sin }^2(2\theta )<0.72$ is in conflict with the recent announcement of a neutrino mass.
