Abstract
A first analysis of the complete set of data collected by CHORUS in the years 1994-1997 is presented. The search for vτ charged current events has been performed for both leptonic and hadronic decays of the τ lepton. No τ candidate has been found. A vμ → vτ mixing is excluded down to sin22θμτ = 6.8 × 10-4 for large Δm2 (90% C.L.).
