Query: Results from the short baseline experiments at CERN   Considerations based on particle physics (in particular the so-called see-saw
mechanism) and on cosmology, in relation to the Dark Matter question, motivated
the search for numu nutau oscillation in the region of small mixing angles. We
present here the outcome of the short-baseline programme carried out at CERN by
the CHORUS and NOMAD experiments. Both experiments are about to publish their
final results. At values of squared mass difference greater than 1 eV2
oscillations between numu and nutau are excluded at 90% C.L. down to mixing
angles values of O(10^{-4}).
