Limits on Muon-Neutrino Oscillations in the Mass Range 30<Δm2<1000 eV2/c4

Abstract

A search for inclusive muon-neutrino (${\nu }_{\mu }$) oscillations has been performed in the Fermilab narrow-band neutrino beam using two detectors running simultaneously at two distances from the neutrino source. The data show no evidence for a distance dependence of the neutrino flux and rule out oscillations of ${\nu }_{\mu }$ into any other single type of neutrino for $30<\mathrm{}\Delta m^2<1000\mathrm{}$ ${\mathrm{eV}}^2$/${\mathit{c}}^4$ and ${sin}^2\left(2\mathrm{}\theta \right)>\mathrm{}0.02-0.20\mathrm{}$.
