Minimal extensions of the scalar sector of the SM can be obtained in order to explore neutrino physics. In particular we are interested in scenarios where the seesaw mechanism for neutrino mass generation could be tested at colliders, thus requiring the right-handed neutrinos to have electroweak scale masses. We present two simple realizations of this type of scheme and explore their scalar phenomenology.
