Abstract

A search for τ lepton production in a sample of 1241 neutrino interactions with use of a hybrid emulsion spectrometer in the Fermilab wide-band neutrino beam is reported. No such events are seen and an upper limit to the νμ-τ coupling of 0.63% (90% C.L.) is set. For νμ-ντ oscillations this sets a limit of |mνμ2- mντ2|<3.0 eV2 (90% C.L.) for maximum mixing.
