New results from a search for $\nu_{\mu} \to \nu_{\tau}$ and $\nu_{e} \to \nu_{\tau}$ oscillation

A first analysis of the complete set of data collected by CHORUS in the years 1994-1997 is presented. The search for $\nut$ charged current events has been performed for both leptonic and hadronic decays of the $\tauu$ lepton. No $\tauu$ candidate has been found. A $\numtonut$ mixing is excluded dow...

Descripción
Sumario:A first analysis of the complete set of data collected by CHORUS in the years 1994-1997 is presented. The search for $\nut$ charged current events has been performed for both leptonic and hadronic decays of the $\tauu$ lepton. No $\tauu$ candidate has been found. A $\numtonut$ mixing is excluded down to $\sin2t$ = $6.8 \times 10^{-4}$ for large $\dm2$ (90\%~C.L.).
