Extending the symmetries of the generalized CP-symmetric 2HDM scalar potential to the Yukawa sector
Sergio Carrolo, Howard E. Haber, Luis Lourenco +1
There are only six independent types of symmetry-constrained (renormalizable) scalar potentials in the two Higgs doublet model (2HDM). For example, the scalar sector symmetry known…
A viable 3HDM theory of quark mass matrices
Iris Bree, Sergio Carrolo, Jorge C. Romao +1
It is known that a three Higgs doublet model (3HDM)symmetric under an exact symmetry is not compatible with nonzero quark masses and/or non-block-diagonal CKM matrix. We show…
Conditions for global minimum in the A4 symmetric 3HDM
Sergio Carrolo, Jorge C. Romao, Joao P. Silva
There has been a great interest in three Higgs doublet models (3HDM) symmetric under an exact A4 symmetry. We provide the complete analytic necessary and sufficient conditions for…
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…
