Description

One of the possible custodial symmetries responsible for naturalness in the Standard Model is conformal (scale invariance) symmetry of the Lagrangian. After a brief review of the Higgs mechanism in the classically-conformal Standard Model, Higgs-portal singlet extensions as a model for dark matter are introduced. Results for the dark matter mass and cosmological abundance predictions in these Higgs-portal models will be presented.
