Query: Constraints on long-baseline neutrino oscillations from the results of
  neutrino oscillation experiments   It is shown that in the two schemes with four massive neutrinos which are
compatible with the results of all neutrino oscillation experiments, the
probabilities of nu_e disappearance and nu_mu->nu_e appearance in long-baseline
experiments are severely constrained.
