Upper limits to. nu. /sub. mu. /-. nu. /sub tau/ oscillation and. nu. /sub. mu. /-tau coupling

Journal Article · · Phys. Rev. Lett.; (United States)
A search for tau 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 ..nu../sub ..mu../-tau coupling of 0.63% (90% C.L.) is set. For ..nu../sub ..mu../-..nu../sub tau/ oscillations this sets a limit of Vertical Barm/sup 2/..mu..-m/sup 2/tauVertical Bar<3.0 eV/sup 2/ (90% C.L.) for maximum mixing.
