Confronting CP symmetry of order 4 with experimental data
Igor P. Ivanov, Duanyang Zhao
CP4 3HDM is a three-Higgs-doublet model based on a symmetry of order 4 (CP4). It is the minimal model incorporating CP4 without leading to accidental symmetries or running int…
SO(10) models with flavour symmetries: Classification and examples
I. P. Ivanov, L. Lavoura
We establish the full list of flavour symmetry groups which may be enforced, without producing any further accidental symmetry, on the Yukawa-coupling matrices of an SO(10) Grand U…
Symmetry breaking patterns in 3HDM
I. P. Ivanov, C. C. Nishi
An attractive feature of New Physics models with multiple Higgs fields is that they are equipped with discrete symmetry groups in the Higgs and flavour sectors. These symmetry grou…
Abelian symmetries of the N-Higgs-doublet model with Yukawa interactions
I. P. Ivanov, C. C. Nishi
We investigate finite abelian groups which can represent symmetries of the N-Higgs-doublet models with quarks. We build a general formalism based on the powerful method of the Smit…
Tree-level metastability bounds in two-Higgs doublet models
A. Barroso, P. M. Ferreira, I. Ivanov +1
The two Higgs doublet model has a rich vacuum structure, including the possibility of existence of two Standard Model-like minima at tree-level. It is therefore possible that the u…
Geometrical CP violation in the N-Higgs-doublet model
I. P. Ivanov, L. Lavoura
Geometrical CP violation is a particular type of spontaneous CP violation in which the vacuum expectation values have phases which are calculable, i.e. stable against the variation…
