Abstract

Neutrino physics is currently suffering from lack of knowledge from at least four major ingredients. One of them is the presence or not of new sterile neutrino states at the mass scale of around 1 eV. Settling this point should be the highest priority for the neutrino community. We will discuss the state-of-the art of experimental searches for sterile neutrinos with accelerators, both at long and short baselines.
