Stability and Symmetry Breaking in the General Two-Higgs-Doublet Model — Markos Maniatis, •Andreas v. Manteuffel, Otto Nachtmann, and Felix Nagel — ITP Heidelberg

A method is presented for the analysis of the scalar potential in the general Two-Higgs-Doublet Model. This allows us to give the conditions for the stability of the potential and for electroweak symmetry breaking in this model in a very concise way. These results are then applied to the Two-Higgs-Doublet potential proposed by Gunion et al. We can clarify the stability and symmetry breaking properties of this model with our method.
