  In recent years, the production of a SM particle with large missing
transverse momentum, dubbed mono-X searches, have gained increasing attention.
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 additional heavier neutrinos with masses at the electroweak
scale are 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 a Higgs boson and missing energy. In this paper, we
address the LHC exclusion power of the latter with dedicated detector
simulations, and reinterpret it in a benchmark scenario for neutrino mass
generation.
