A search for $\nu_{\mu} \leftrightarrow \nu_{\tau}$ oscillations using the NOMAD

This talk presents the current status of the search for nu /sub mu / to or from nu /sub tau / oscillations with the NOMAD detector. Significant progress has been made with respect to our published results. The analysis techniques have been improved and a larger data sample, corresponding to the 1995-1997 runs has been used, The search yields no evidence of the presence of oscillations. The updated limit on the neutrino oscillation mixing angle is sin/sup 2/2 theta /sub mu tau /<1.2*10/sup -3/, in the limit of large Delta m/sup 2/. (6 refs).
