Description
We discuss the interplay between the Inert Higgs Doublet (IDM) dark matter and a vector-like SU(2)_L triplet lepton (VLL), both of which are odd under $Z_2$ symmetry. A compressed mass spectrum and a sufficiently small Yukawa coupling allows co-annihilation and late decay of the VLL into the IDM sector, which affects the relic density of the pseudoscalar dark matter. The same two factors enable displaced decay of the VLL states, providing novel signatures involving hadronically quiet displaced multi-lepton final states. Such signatures to probe the model are studied at the 14 and 27 TeV LHC, as well as the 100 TeV FCC-hh. The detection possibilities at the CMS, ATLAS and the proposed detector MATHUSLA are thoroughly explored.
