A tale of twin Higgs: natural twin two Higgs doublet models
- Univ. of Massachusetts, Amherst, MA (United States). Dept. of Physics. Amherst Center for Fundamental Interactions
In original twin Higgs model, vacuum misalignment between electroweak and new physics scales is realized by adding explicit Z2 breaking term. Introducing additional twin Higgs could accommodate spontaneous Z2 breaking, which explains origin of this misalignment. We introduce a class of twin two Higgs doublet models with most general scalar potential, and discuss general conditions which trigger electroweak and Z2 symmetry breaking. Various scenarios on realising the vacuum misalignment are systematically discussed in a natural composite two Higgs double model framework: explicit Z2 breaking, radiative Z2 breaking, tadpole-induced Z2 breaking, and quartic-induced Z2 breaking. Finally, we investigate the Higgs mass spectra and Higgs phenomenology in these scenarios.
