Suppression of Higgs mixing by “quantum Zeno effect”
Abstract The Higgs portal interaction to a singlet sector of the standard model (SM) gauge group is widely-studied. In this paper, we show that a quantum effect is important if the Higgs field mixes with another singlet scalar field whose decay rate is larger than the mass difference between the two...
