abstract
The discovery of the Higgs boson suggests that also neutrinos get their mass from spontaneous symmetry breaking. In the simplest ungauged lepton number scheme, the Standard Model (SM) Higgs has now two other partners: a massive CP-even, as well as the massless Nambu-Goldstone boson, called majoron. For weak-scale breaking of lepton number the invisible decays of the CP- even Higgs bosons to the majoron lead to potentially copious sources of events with large missing energy. Using LHC results we study how the constraints on invisible decays of the Higgs boson restrict the relevant parameters, substantially extending those previously derived from LEP and shedding light on spontaneous lepton number violation.

Electroweak Breaking and Higgs Boson Profile in the Simplest Linear Seesaw Model
In the simplest linear seesaw model, astrophysical, unitarity, and LHC constraints force a compressed scalar spectrum and permit the 125 GeV Higgs to decay invisibly into majorons with branching ratios up to about 20%.
