Symmetry and decoupling in multi Higgs models
Sérgio Carrôlo, Jorge C. Romão, João P. Silva +1
We study the scalar sector of the most general multi Higgs doublet model satisfying explicitly an exact symmetry. We prove that such a model will exhibit decoupling if and only if…

Yet another lesson on the stability conditions in multi-Higgs potentials
Igor P. Ivanov, Francisco Vazão
We discuss a rather common but often unnoticed pitfall which arises when deriving the bounded-from-below (BFB) conditions in multi-Higgs models with softly broken global symmetries…
