Sumario:We have completed the "Phase I" oscillation analysis for the entire CHORUS data set, taken in the years 1994-1997, the search for nu /sub tau / charged current events has been performed for both muonic and hadronic decays of the tau lepton. No tau candidate has been found in "Phase I" analysis. The nu /sub mu / to nu /sub tau / mixing is excluded down to sin/sup 2/2 theta /sub mu tau / = 6.8 * 10/sup -4/ for large Delta m/sub mu tau //sup 2/ using a statistical treatment. The analysis continues ("Phase II") with a new techniques, developed in DONUT experiment to improve the sensitivity.
