| Résumé : | CHORUS is an experiment searching for νμ → ντ oscillation in the CERN wide band neutrino beam with a hybrid setup consisting of a nuclear emulsion target followed by electronic detectors. The experiment has been taking data from 1994 through 1997. A subset of the neutrino interactions collected in 1994 and 1995 have been analyzed, looking for ντ charged current interactions where the τ lepton decays to μν̄μντ. In a sample of 31,423 νμ charged current interactions, no ντ candidates were found. For large Δm2μτ values, a limit on the mixing angle of sin22θμτ < 3.5 × 10-3 at 90% C.L. can be set, thus improving the previous best result. © 1998 Elsevier Science B.V. |
