Abstract

We consider a class of singlet scalar extensions of the Standard Model of particle
physics in which the scalar couples only to of-shell states. As a result, low-order tree-level processes involving the singlet scalar vanish, providing a unique phenomenology that may allow to evade existing constraints on new singlet scalar felds. We describe search strategies for such states at the Large Hadron Collider and identify the parameter space that can be explored in the future.
