Abstract
A first analysis of the complete set of data collected by CHORUS in the years 1994-1997 is presented. The search for nu /sub tau / charged current events has been performed for both leptonic and had onic decays of the tau lepton. No tau candidate has been found. A nu /sub mu / to nu /sub tau / mixing is excluded down to sin/sup theta / 2 theta /sub mu tau /=6.8*10/sup -4/ for large Delta m/sup / (90% C.L.) (27 References).
