• #### CP-Violation in the $ZZZ$ and $ZWW$ vertices at $e^+e^-$ colliders in Two-Higgs-Doublet Models ﻿

(Springer, 2016-05)
We discuss possibilities of measuring CP violation in the Two-Higgs-Doublet Model by studying effects of one-loop generated $ZZZ$ and $ZWW$ vertices. We discuss a set of CP-sensitive asymmetries for $ZZ$ and $W^+W^-$ ...

• #### Diagnosing CP properties of the 2HDM ﻿

(Springer, 2014-01)
We have investigated a Two-Higgs-Doublet Model (2HDM), focusing on CP violation. Various scenarios with spontaneous and explicit breaking of CP have been considered. Some features of CP violation related to a choice of the ...

• #### Measuring CP violation in two-Higgs-doublet models in light of the LHC Higgs data ﻿

(Springer, 2014-11)
In Two-Higgs-Doublet models, the conditions for CP violation can be ex- pressed in terms of invariants under U(2) rotations among the two SU(2) Higgs doublet fields. In order to design a strategy for measuring the ...

• #### A simple method to detect spontaneous CP violation in multi-Higgs models ﻿

(Springer, 2017-08)
For models with several Higgs doublets we present an alternative method to the one proposed by Branco, Gerard and Grimus, in 1984, to check whether or not CP is spontaneously violated in the Higgs potential. The previous ...

• #### Spontaneous symmetry breaking in the S3-symmetric scalar sector ﻿

(Springer, 2016-02)
We present a detailed study of the vacua of the S3-symmetric three-Higgs-doublet potential, specifying the region of parameters where these minimisation solutions occur. We work with a CP conserving scalar potential and ...
