Hiding the Higgs Boson with Multiple Scalars

Abstract

We consider models with multiple Higgs scalar gauge singlets and the resulting restrictions on the parameters from precision electroweak measurements. In these models, the scalar singlets mix with the SU(2) Higgs doublet, potentially leading to reduced couplings of the scalars to fermions and gauge bosons relative to the Standard Model Higgs boson couplings. Such models can make the Higgs sector difficult to explore at the LHC. We emphasize the new physics resulting from the addition of at least two scalar Higgs singlets.
