Abstract

Updated results from the appearance searches for $\numunutau$ and $\nuenutau$ oscillations in the full NOMAD data sample are reported. The increased data and the use of more refined kinematic schemes for the $\nutau$ CC selection allow a significant improvement of the overall sensitivity. The ``blind analysis" of both the deep-inelastic and the low multiplicity samples yields no evidence for an oscillation signal. In the two-family oscillation scenario, this sets a 90\% C.L. region in the $\sin^22\theta_{\mu\tau} - \Delta m^2$ plane which includes $\sin^22\theta_{\mu\tau}\ \ 4.4\times10^{-4}$ at large $\Delta m^2$ and $\Delta m^2 0.8$ eV$^2$/$c^4$ at $\sin^22\theta_{\mu \tau}=1$. The corresponding contour in the $\nuenutau$ oscillation hypothesis results in $\sin^22\theta_{e\tau}\ \ 2.2\times10^{-2}$ at large $\Delta m^2$ and $\Delta m^2 6.5$ eV$^2$/$c^4$ at $\sin^22\theta_{e \tau}=1$
