Are There Hidden Scalars in LHC Higgs Results?

Understand

The Higgs boson recently discovered at the Large Hadron Collider has shown to have couplings to the remaining particles well within what is predicted by the Standard Model.

• The search for other new heavy scalar states has so far revealed to be fruitless, imposing constraints on the existence of new scalar particles.
• However, it is still possible that any existing heavy scalars would preferentially decay to final states involving the light Higgs boson thus evading the current LHC bounds on heavy scalar states.
• Moreover, decays of the heavy scalars could increase the number of light Higgs bosons being produced.
