Sommaire:

In recent years, the production of a SM particle with large missing transverse momentum, dubbed mono-X seraches, have gain increasing attentions.
After the discovery of the Higgs boson in 2012, the run-II of the LHC will now scrutinise its properties, looking for BSM physics.
In particular, one could search for mono-Higgs signals, that are typically studied in models addressing dark matter. However, this signal can appear also in models addressing the neutrino masses, if a heavier neutrino is present. The latter will couple to the SM neutrinos and the Higgs boson, yielding a type of mono-Higgs signal not considered for dark matter: the resonant production of Higgs + missing energy.
In this talk I will describe the resonant mono-Higgs channel, the LHC exclusion power, and present a benchmark model for the reinterpretation. Finally, I will conclude by presenting a survey of the complementarity of a future lepton collider.
