Description
The mirror twin Higgs framework allows for a natural Higgs mass without the need for colored partners. This mechanism relies crucially on a discrete symmetry which relates each standard model field to a mirror partner. In the minimal realization, the twin Higgs scenario provides only one low-energy connection between the visible and twin sectors, the light Higgs boson. In this talk, I will present a new class of portals connecting the two sectors, using fields that have 'no twin' partner under the discrete symmetry. Scalar, fermion, and vector states may provide such 'singleton' portals. Each with unique features and experimental signatures. The vector portal, in particular, provides a variety of renormalizable interactions relevant for LHC phenomenology. I will discuss a concrete construction of these the vector portal and discuss its phenomenology.
