A Search for $\nu_\mu \to \nu_\tau$ Oscillation

CHORUS is an experiment searching for $\numtonut$ oscillation in the CERN wide band neutrino beam with a {\sl 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 coll...

Descripción
Sumario:CHORUS is an experiment searching for $\numtonut$ oscillation in the CERN wide band neutrino beam with a {\sl 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 $\nu_\tau$ charged current interactions where the $\tau$ lepton decays to $\mu \bar{\nu}_\mu\nu_\tau$. In a sample of 31,423 $\num$ charged current interactions, no $\nu_\tau$ candidates were found. For large $\dm2$ values, a limit on the mixing angle of $\sin2t < 3.5 \times 10^{-3}$ at $90\%$ C.L. can be set, thus improving the previous best result.
