Sommaire:

The observation of Higgs decays into heavy neutrinos would be evidence for new physics associated to neutrino masses. We study such decays within the type I seesaw mechanism in the GeV mass range via displaced vertices and explore the region of parameter space where they can be measured at the LHC. We show that, after imposing pseudorapidity cuts, there is a region where the number of events is larger than O(10).
