Abstract
Non-resonant production of Higgs-pair via heavy intermediate states may be a distinctive signature for extended discrete symmetries when accompaied by large missing transvers energy. We discuss -parity as an example of such symmetry within the Littlest Higgs Model, where a new heavy gauge boson , the -odd partner of SM -boson, predominately decays into to a Higgs boson and a dark matter candidate . In essence, -parity stablises simultaneously both the Higgs mass and the dark matter. Production via may therefore yield important clues about symmetries connecting the Higgs and dark sectors. This paper makes a case for the search for this channel at the LHC by studying its discovery potential. It is demonstrated that in situations where a large mass gap results in a boosted topology, the jet-substructure technique can be leveraged to reach the required significance for discovery in the decay mode.
