Search for heavy neutrinos mixing with $\tau$ neutrinos / NOMAD Collaboration
We report on a search for heavy neutrinos ($\nus$) produced in the decay $D_s\to \tau \nus$ at the SPS proton target followed by the decay $\nudecay$ in the NOMAD detector.\ Both decays are expected to occur if $\nus$ is a component of $\nu_{\tau}$.\ From the analysis of the data collected during the 1996-1998 runs with $4.1\times10^{19}$ protons on target, a single candidate event consistent with background expectations was found.\ %No evidence for this decay chain has been found This allows to derive for the first time an upper limit on the mixing strength between the heavy neutrino and the tau neutrino in the $\nus$ mass range from 10 to 190 $\rm MeV$.\ Windows between the SN1987a and Big Bang Nucleosynthesis lower limits and our result are still open for future experimental searches.\ The results obtained are used to constrain an interpretation of the time anomaly observed in the KARMEN1 detector..

A More Sensitive Search for $\nu_{\mu} \to \nu_{\tau}$ Oscillations in NOMAD / NOMAD Collaboration
With additional data and improved algorithms, we have enhanced the sensitivity of our appearance search for $\numunutau$ oscillations in the NOMAD detector in the CERN-SPS wide-band neutrino beam. The search uses kinematic criteria to identify $\nutau$ charged current interactions followed by decay of the $\tau^-$ to one of several decay modes. [...]

Precision Measurement of Scaled Momentum, Charge Multiplicity and Thrust in $\nu_{\mu}N$ and $\overline\nu_{\mu}N$ Interactions / NOMAD Collaboration
We report the first precision measurements of the scaledmomentum, the charge multiplicity, and the thrust of hadronic jets inthe Breit frame in Deep Inelastic Scattering \nun\ and\nunbar\ charged current events over the $Q^2$ range from 1 to 100 \GeVsq\ . Theneutrino data, obtained in the NOMAD experiment at the CERN SPS, extend the $Q^2$-evolution ofthese parametersby two orders of magnitude, and with commensurate precision, whencompared to those reported by the \ep\ and \ee\ experiments..

A search for $\nu_{\mu} \rightarrow \nu_{\tau}$ oscillations using the NOMAD detector / NOMAD Collaboration
NOMAD is a neutrino oscillation experiment designed to search for $\nu_\tau$ appearance in the CERN-SPS wide band $\nu_\mu$ beam. Signal detection relies on the identification of $\nu_\tau$ charge d current interactions using kinematic criteria. [...]

Search for a new gauge boson in $\pi^{0}$ decays / NOMAD Collaboration
A search was made for a new light gauge boson $X$ which might be produced in $\pi^{0}\to\gamma + X$ decay from neutral pions generated by 450-GeV protons in the CERN SPS neutrino target. The X's would penetrate the downstream shielding and be observed in the NOMAD detector via the Primakoff effect, in the process of $X \to\pi^{0}$ conversion in the external Coulomb field of a nucleus.

The NOMAD experiment at the CERN SPS / NOMAD Collaboration
The NOMAD experiment is a short base-line search for $\nu_{\mu}\rightarrow \nu_{\tau}$ oscillations in the CERN neutrino beam. The $\nu_{\tau}$'s are searched for through their charged-current interactions followed by the observation of the resulting $\tau^{-}$ through its electronic, muonic or hadronic decays. [...]
