摘要：

There are several independent hints for neutrino oscillations with a mass-squared difference at the eV(2) scale. If confirmed, this would imply the existence of sterile neutrinos. I discuss the present status of the hints for nu(e) disappearance from reactor experiments and Gallium source experiments, as well as from the LSND and MiniBooNE nu(mu) -> nu(e) appearance searches. A consistent interpretation of the global data in terms of neutrino oscillations is challenged by the non-observation of a positive signal in nu(mu) disappearance experiments. There is a strong tension in the global data, irrespective of the number of eV-scale neutrino states.
