Abstract content

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 masses around the electroweak scale and potentially large neutrino Yukawa couplings, which makes them testable at planned future particle colliders.

The presented poster shows a systematical discussion of the production and decay modes at electron-positron, proton-proton and electron-proton colliders and provides a complete list of the leading order signatures for sterile neutrino searches. Among other things, several novel search channels are provided, and a first look at the possible sensitivities for the active-sterile mixings and the corresponding heavy neutrino mass range is given. The poster shows the comparison of the performance of the different collider types which is essential for the discussion of their complementarity.
