Description
Sterile neutrinos are among the most attractive extensions of the SM to generate the light neutrino masses observed in neutrino oscillation experiments. When the sterile neutrinos are subject to a protective symmetry, they can have Majorana masses around the electroweak scale and potentially large neutrino Yukawa couplings, which makes them testable at the planned Future Circular Colliders. In this talk I outline a systematic assessment of the signatures for sterile neutrino searches at electron-positron, proton-proton and electron-proton colliders. I present preliminary results on foreseeable sensitivities of the most promising signatures and compare the performance of the different collider types.
