Description
We propose a UV-completion of the inverse see-saw scenario using fermion SU(2)L triplet representations. Within this framework, a variation of the standard thermal leptogenesis is achievable
at the O(TeV) scale, owing to the presence of a viable Dark Matter candidate. This baryogenesis scenario is ruled out if a triplet fermion is observed at the LHC. The Dark Matter is given by
the lightest neutral component of a complex scalar SU(2)L triplet, with mass mDM > 1290 GeV. The scalar sector, which is enriched in order to account for the small neutrino masses, is treated
in detail and shows potentially sizable Higgs boson h → γγ rates together with large h invisible
branching ratios.
