Higgs properties in the Stealth Doublet Model

I present a model with two scalar doublets and a softly broken ℤ2 symmetry, where only one of the doublets gets a vacuum expectation value and couples to fermions at tree-level. The softly broken ℤ2 symmetry leads to interesting phenomenology such as mixing between the two doublets and a charged scalar H± which can be light and dominantly decays into Hγ. The model can also naturally reproduce an enhanced γγ signal of the newly observed Higgs boson at the LHC with mass 125 GeV.
