Higgs properties in the Stealth Doublet Model    [PDF]

Glenn Wouda

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